2180miles Trailhawk on the Smith-Dorrien Trail by 2180miles

----------


Hey all!

So this is my formal introduction here after quite a while following along on here and Instagram. This is a cross-forum build, but I figured some of you guys might be interested in reading along with the build-up of a less common vehicle platform. My name is Ryan, and my username is as such due to my endurance adventure blog that I write with stories of my 2014 Appalachian Trail thru-hike, 2007 cross country bicycle trip, and winter 2016 (never before completed, and unfortunately unsuccessful) attempt at Vermont's 273 mile Long Trail. I'm definitely disappointed that one ended early, but you can go read about it and see photos if you'd like: www.2180miles.com

I'm a decade long TJ owner, having sold my Volvo 840 buying my Wrangler Sport in high school, and building her since then. She's up on 35" MTR/Ks, 3" lift with Currie suspension, 8k Smitty winch, Undercover Fab aluminum skids from front to back, Rigid LEDs everywhere, strobe lights for on-road recovery stuff (good samaritan lights as I call them) and the rest of the typical works with electronics and radios. The members of the Massachusetts Jeep club I founded in 2011 affectionately call her Big Red. As our club has grown, my close group of Jeep friends began discussing an overland trip through northern New England. As I took on the planning of our adventure with my buddy Rob, I began realizing that the TJ wasn't going to be the best platform for me personally to do these kinds of trips in.

I began shopping for a JKUR, floating the idea of trading my daily driver in and keeping the TJ and the JKUR, each to serve different purposes. As my research continued and I spoke with JKUR owner friends, I realized that I'd much rather have something along the lines of an SUV that would be less of a one trick pony. I travel for work and therefore frequently have rental cars, so I began test driving the Grand Cherokees during my weeks away from home, which ultimately turned my search in that direction. Reading about the 2016 and (at the time) new models for 2017, I focused on the Overland and Trailhawk trims as ones I'd be interested in buying. Price was a factor, but I knew early on that I didn't want to heavily mod this truck, so buying a Limited trim and upgrading things wasn't really in the cards for me. The Overland is much more of a luxury oriented vehicle than the name might suggest, and the Trailhawk is the nitty gritty, but still very well equipped, model.

After many months of waiting, debating, test driving, yada yada, I finally went ahead and purchased a 2017 Trailhawk this past January. Fully loaded (minus Blu-Ray entertainment), it was a unique package with the active safety package, luxury package - read: panoramic sunroof that I dreamed about, multiple skid plates underneath, 18" wheels wrapped in Kevlar lined Goodyear A/Ts, and the Quadra-Trac/air suspension package. Sticker was $49,500, and after a week of putting dealerships against each other, and after a bit of negotiating I got it from a dealer in New Hampshire (90 minutes from my house in Boston), for $42,799. I am quite happy with the price, and opted to add the 7-year bumper to bumper Mopar warranty for $1,300 for a piece of mind. There's a high likelihood I keep it that long, and I can get money back from FCA if I sell the vehicle first.

So that's probably enough for post #1. I purchased it and dropped it off immediately for the front end to be protective wrapped, so I haven't had a chance to take it for a real high-res photo shoot yet (save for lining the ladies up for a family photo as you'll see below). Here are some photos to start, since that's what we all love in these threads anyway. This will not be the most advanced or capable build in the history of this forum, but aside the rare iPhone photo, I promise to at least have high quality pictures.

Lots of updates to come, since I'm about 9 months into this build at this point, but we'll take it one thing at a time!

Nice!

Thanks man! I've been enjoying following your build on IG as well.

 

[2180miles]

First up on the mods list (I guess removing the license plate bracket happened first) was to get the front end protective wrapped against road rocks and paint chips. I had been meaning to do this on the A4 when I purchased, but never got around to it. I had only had the GC home for 12 hours before I drove it a few miles and dropped it off at a local shop that has Lambos, Ferraris, and Porsches as his regular detail / wrap clients. In discussing my options with Pete, the owner of Unique Car Care, even before I took delivery of the Trailhawk, he laid out three options for protective packages that I could go with.

For $799 I chose the Xcel self-healing/UV safe/10 year warranty protective wrap for the full front bumper, grille, 1/3 hood, 1/3 front fenders, and mirrors. He even used a special "stealth black" to cover the hood decal to match the hood wrap line. In addition to this I had him do the b-pillars to protect the glossy black material from scratches, then the a-pillars and the roof line before the sun roof. My intention with the latter two was to protect the paint from scratches that I might encounter when on trails as the roofline lifts the low hanging branches up. I know a lot of you have access to wide open trails and beautiful mountain ranges, but in New England we have a ton of heavily wooded trails with overgrown vegetation that often lends pin striping to the paint jobs of our rigs.

Total cost with the pillars/roof add-ons and a detail job after the install - $1,049.00... Might seem steep, but with the road and trail miles I intend on putting on this, I think protecting it right off the bat was the only decision. Beneficial for me, he kept the car in his shop all week while I've been gone.

Here are some photos he sent me during the install...

So the next thing up on the mods list was a CB. Our club has a requirement for CB radios during group events and trail runs, and while I'm not entirely sure yet that the Grand will replace the TJ on those easier runs, it's still important for me to have it. I've been planning to take the amateur exam and eventually installing a 2m/440 system in the truck, but haven't gotten around to that yet. For now, a few miles of coms is all I need on a regular basis. For better or worse, there's not a ton of information on CB installs in the WK2 models. A handful of photos here and there of antenna mounts, and a bit of HAM installs, but I figured I'd go ahead and of a more detailed write-up for anyone else that may need it in the future.

In order to maintain a clean look for the cabin, and to occupy as little floorspace as possible, I chose the Cobra 75WX unit. The system is pretty much contained in the mic itself, with scan and weather functions, and has a separate box that converts the PL-259 coax to the mic cable, also adding an external speaker 1/8" jack (the 75WX is known for a weak speaker, since it's contained in the microphone itself... for now, it'll be fine, but I'll eventually put a speaker under one of the seats for a little more oomph). I also chose a 2' antenna with the approximate knowledge that when mounted on a spring by the bracket, I would get the top of the antenna about 8" over the roofline. While this isn't fantastic for any antenna, it will give me adequate reception and will still maintain a clean OEM+ look (it'll also be able to fit in the lower bay of my garage if ever the need arose, and I can easily swap in a taller antenna for trips with the club.

From the images I found on google, it seems most people rivet or velcro a mic clip into the center console or on either side of the 8.4" screen, but I wanted something that was a little more easily accessible and didn't require drilling a hole in the dash or the tacky look of an adhesive. I started searching for a cell phone type mount specific to the Grand Cherokee, and discovered the ProClip Console Mount which was designed to mate up to the center console by the cup holders. They provide a small tool to pop up the console and get the lip of the clip underneath for secure mounting. It took all of 2 minutes to get this thing hooked up, including drilling out and screwing in the mic clip that Cobra provided with the CB.

Photos of other owners who have tailgate mounted antennas on the WK2 have shown them in two locations, 1 being drilled into the brake light assembly, and the other into the lower bumper below the brake light. In both instances the antenna is mounted into plastic, so I went ahead and ordered a NGP (no ground plane) antenna from Firestik. This is a special kind of antenna where the internal wiring is designed to work at locations that do not have metal ground planes, like motorhome fiberglass, on a motorcycle where the metal is minimal, and on boats. In this instance it worked perfectly for my plastic brake light.

I initially was hesitating to drill into the brake light itself but after removing the plastic pop rivets and taking the light off the Jeep, I realized that there was plenty of room to get a metal bracket on the back side of the mount in between the tail light's plastic. I cut up a small piece (1.5" x 1.5" , if that) of 18 gauge steel to provide a firm backing to the antenna bracket. Drilling it out to the same hole pattern as the bracket I was then able to use the self-tapping screws to get through the mount, plastic brake light, and metal on the other side. I painted the metal plate and put it front of my heat gun to speed up the drying. Putting this back onto the Jeep I was able to close the tail gate and check that there were no clearance issues between the two when it closed. Initially there was a little bit of rubbing (against the tail gate side plastic, not metal thankfully!) so I took the bracket to my angle grinder with a flapper disc and smoothed it down a bit to cut down on rubbing.

Next up in the process was figuring out how to get the coax cable back to the CB itself. I had decided from the beginning that the CB controller box would live under the battery compartment lid (the battery on the WK2 is under the passenger seat... makes 12v wiring a breeze), so the coax needed to end up there. I fed the wire through the vents in the back of the trunk, then used my interior trim tool kit to lightly bend the trim pieces and push the wiring underneath. I moved from the rear pillar to the trim piece at the very back of the trunk, then around to the passenger side. I had to unbolt the cargo tie down to lift the right side of that trim piece up, but then was able to feed the wire down along the spare tire compartment to behind the rear bench seats. Moving to the rear passenger door, I fed the coax under the door trim and then under the passenger seat bracket and into the battery compartment. It took a while to get all of this done, using patience as I was petrified of breaking a trim panel on the brand new truck, but I managed to use all 18' of the wire without any coils or major stuffing of any spare wire... all good things for signal! It's also nice that the only time the cable is exposed is the 2" between the B-pillar and the front passenger seat, and the location where it passes through the tailgate weather strip.

Once that was done, I went to check in on my buddy Rob who had been going to town with the battery compartment cover. Cobra includes a nice grommet and mount for the wire, so we decided that instead of mounting the control box on the top of the compartment cover, we'd mount it underneath. Due to where the battery lives there was a lot of room to the left side, where the control box fit perfectly. Simple crimp-on ends were easily attached to the (+) lead of the battery, and we grounded it out to the seat bracket for a good chassis ground. Drilling out the compartment cover to run the mic control cable under the seat, we then threw the grommet in there and called it good. The nice thing about this CB is that the microphone can detach from the control box so if I ever need to get it out of the way for whatever reason, it's simple to do so.

Here are the photos of the wiring (I labeled the route in red) and the under-seat bracket and wiring.

After this it was a matter of getting the antenna assembly onto the rear bracket, and tuning it. While Firestik tunes their CB antennas from the factory, I find it's always best to re-do the tuning on the vehicle itself to find out how the environment and install have affected its signal. The yellow band at the base of the antenna in some photos is there to denote that is is a NGP antenna and will not function normally on a standard CB antenna install. Once tightened down on the bracket and the tailgate operation was tested a few times, we took the Jeep out to the end of a state park where marshlands surround the parking lot for quite a distance in every direction. This area provides an uninterrupted surrounding for the antenna to be tuned in, not affected by power lines, buildings, or other structures that can cut down on the reception and SWR readings.

After toying around with the adjustable antenna screw for a while, Rob and I were quite pleased to have the CB measure in at around 1.2 - 1.5 SWR at channels 1, 20, and 40. In my many experiences installing CBs in my Wrangler (I've used 3, 4, and 5' antennas, so I've done a bit of tuning) and installing them in dozens of friend's rigs, this was the quickest and cleanest install to SWR readings I've ever come across. I was quite pleased. I took some photos of the Jeep while we were out there, and let Rob mess around with the air suspension, dropping it into it's lowest settings (which I hadn't yet done) and raising it up to Off-Road 2 mode, it's highest setting.

After returning back to his house, packing up my stuff and leaving, he sat in the cab of his Tacoma and we did a range-test between our radios as I drove away. I knew going into this that the 2' antenna would be a limiting factor on range, but I was happy to find that I could hear him clearly and he could receive me clearly up to around 2 miles away as the crow flies. I had measured out distances from his house online beforehand to know which landmarks marked which distances. So, a few hours and about $150 and I have a solid CB set-up in the Grand, with a range that will do just fine for what I need it for.

Hopefully this will help someone out in the future if they are doing the same thing to their WK2.

Big thanks to Rob for helping out. Here are the final photos of it installed.

Couple weeks went by, I swapped the included Firestik spring with an HD spring as it was bending backwards at highway speeds. Easy swap, no issues since then.

Next up after that... recovery points for the rear end of the rig.

While the forward bumper of the Trailhawk is adorned with red powder coated tow hooks, a large part of the aggressive appearance of the vehicle's front end, the back has nothing readily available but a trailer hitch receiver. In the interest of being ready for things like trail recovery scenarios, I wanted to put something in the hitch to allow for being yanked backwards if ever necessary. While Harbor Freight has their classic $19 option, but obviously it isn't really an option at all.

After scouring the internet I recognized a name from the ExpoOverland guys front bumpers - Factor 55. They've since become a partner/sponsor in the Trailhawk build, for which I'm incredibly grateful.

A product by the name of "Hitchlink" caught my eye as the perfect solution to my needs for a rear recovery point. A block of aluminum weighing in at just under 2 pounds and rated to 9,500lbs , this thing is a beast. Their website depicts the ultimate failure point at 51,000 pounds... a point by which the trailer hitch and frame would have been yanked out from underneath the WK2. With a multitude of color options I rolled the dice for the dark grey to match Halley, and was quite pleased to find that it did. I bought some powder coated red 3/4" shackles to add a nice accent to the back of the Hitchlink, keeping with the grey/red theme of the entire vehicle. A few minutes on Amazon found me a locking hitch pin, since I've now got nearly $120 into my rear recovery point... not something I'm ready to have stolen off the back end of the Jeep.

While on Amazon I also picked up a 125-piece first-aid kit for a whopping 20 bucks. Never a bad thing to have, and it even goes so far as to include a glow stick and space blanket. Hopefully never are needed, but for now they're stored in the nifty zipped up kit in the trunk's spare tire organizers.

Pictures, cause that's what people care about... :)

Does that 1st aid kit have a turniquet or an Israeli bandage in it? Hopefully they wouldn't be the most used items in the kit but to me the 2 most important items!

Honestly I don't think it does, but I have spare load straps and synch straps right near to it if ever need be. Easily accessible, 1.5" diameter.

Mid-spring last year I went ahead and had some vinyl lettering done for the rear side windows to hopefully drive some traffic to the blog and social media accounts. The lettering/logo measure 22" wide and 4" tall. I found a place called Sticker Genius on the web who printed me 3 copies of the sticker (1 as a backup) for $35 delivered. I went ahead a few months later and got a wide banner across the top of the rear window, but I wanted to get this done first so that I could see what would look best on the back.

Looks pretty clean, in my opinion.

After that came a rather cool update for the WK2 build...

In March of '17 I reached out to an Austrailian company called Chief Products who makes skid plates, push bars, etc. for the Grand Cherokee platform. Reading about their recessed winch mount, and noting their comments about looking for a 2017 M.Y. & Trailhawk platform test vehicle, I emailed them volunteering myself to assist with the test-fitting of their new WK2 Hidden Winch Mount. In a few long e-mails back and forth between myself and Bill, the owner of Chief Products, we decided that he'd ship me one of their winch mount systems at a reduced rate in exchange for install and final-product photos, and measurements of the fitment within the 2017's new sloped grill style. This was an immense first step in making the Grand more capable on its own.

Knowing that this winch mount would need a winch to go in it, I reached out to Warn and asked about their corporate sponsorship opportunities for the Trailhawk build. In doing a fair amount of research and speaking with Bill at Chief about what winches he already knew fit the mount, it became pretty clear that the Warn Zeon Platinum was going to be the most ideal option for the WK2. Yeah, okay, it's insanely expensive - $1750 - (this especially emphasized due to me being a guy who has rocked a Smittybilt XRC-8 for 6 trouble free years on the front of my TJ), but the Platinum is the best winch on the market in Warn's 4WD product line, and has one key quality that will prove immensely useful in the Grand Cherokee: an electronic clutch. Once this puppy is recessed into the front end, accessibility of the free spool/engage clutch would become rather difficult as far as I can tell. It's waterproof, wifi-based remote operable, has an accessory 12v port for driving lights (bypassing the need to run wiring through the firewall) and is wound with the Spydura Synthetic line. After a few e-mails with a woman in the sponsorship department at Warn, she informed me that while they couldn't give me a Zeon Platinum for free, she could send me one at a deeply discounted rate. So for over a thousand dollars under retail, I'll have the most highly regarded unit they're currently manufacturing in the front end of the WK2 on the Chief Products mount.

These, combined with a FrontLink winch hook courtesy of Factor55 which I'm equally excited to install, will transform the front end and my self-recovery abilities immeasurably. For now I've got some stock imagery, but should have some great photos coming when I tackle the install with my buddy Rob in a few weeks. In the mean time, I'm pretty excited for these upcoming modifications to the rig.

Add them while those straps will work the modern ones are much better and easier to use! You can get them and israeli bandages on Amazon pretty cheap.

[2180miles]

At the beginning of last May, over the course of two afternoons and evenings, my buddy Rob and I dove into the installation of the Chief Products Hidden Winch system in the front end of my WK2 Grand Cherokee Trailhawk. I had been speaking with Bill Mackin, the owner of Australia-based Chief Products, since the beginning of March in regards to getting one of their mounts test-fitted in a 2017 Grand Cherokee to see what kind of adjustments, if any, would need to be made for the new generation grills and front-ends. I reached out to Warn to inquire as to sponsorships for a winch, and after speaking with someone from their Sponsorship team, was offered a steep discount on the 10-S Platinum for installation on the Trailhawk.

*It’s important to note that this installation is not representative the Chief Products final version of the Hidden Winch system, as they were still getting information from me about what does and does not work with the 2017 GC model I installed it on. This is especially important as it pertains to fitment and trimming. As of my writing this they’re reviewing the notes/write-up and seeing what changes may need to be made to the assembly*

-----

Having never taken the front end off of the Jeep before, and being used to the much more accessible front end of a Wrangler, I did some research as to what went into taking the lower fascia and the upper bumper off. Chief Products had a good write-up for the fascia, and a quick YouTube video showed how simple it was to remove the bumper… we were in business. It’s easy enough, with a few quarter-turn screws under the fascia, two plastic rivets per side in the wheel well, the fascia then pops off from the bumper. The bumper itself requires removing a small hex-head nut in each wheel well, and two small plastic rivets along the top of the radiator brace bar.

We decided to do the installation at Rob’s house, as I’m still in the process of getting my garage at home organized enough and he has a large driveway that easily accommodated our needs. I opened the shipping boxes and laid out our components on an old section of drywall he had in the shop, and we took inventory of what we had to work with.

From there we disconnected the ACC camera via the two fasteners that hold it to the bottom of the OEM bumper. There’s a small wiring harness that needs to be unclipped, then it was placed to the side well out of harms way (I don’t want to know how much that camera costs). We then went about removing all of the fasteners that hold the OEM bumper to the Jeep itself, as highlighted by the red circles in the photo below. With the Styrofoam bar and metal backing removed, we took off the plastic protecting pieces from the air suspension system and the windshield washer fluid reservoir. Last to do here was remove the air duct pieces from in front of the radiator, and move the wiring looms as far out of the way as possible for access to the front end.

The majority of the Chief Products Hidden Winch system is comprised of 3 main pieces (comprised of 5 individual parts). The winch cradle spans the mid-section in front of the radiator, and holds the winch in place. There are two frame mount brackets, one for each side, and finally two tow-hook mounting brackets that sandwich between the cradle and frame brackets. By starting with the frame brackets, installing the mounting fasteners without tightening down, we were able to then install the tow hook pieces and the winch cradle without issue, putting the hardware in to hold the entire assembly together while we figured out how the other pieces assembled.

This was getting towards the end of our first day (night, actually… we were working by the light of the flood light in the driveway) and we were both pretty tired. We struggled for a while with the tow hooks before I called Bill at Chief Products and asked him if we were missing something. In hind sight, had we played around a bit more with the pieces we would have realized that the OEM tow hooks need to be swapped to the opposite side of their original installation location, and flipped over to work with the new brackets. Laymen’s terms: move the driver hook to the passenger side, passenger hook to the driver side, flip 180 degrees, and install to Chief Products tow hook spacers.

At that point we called it a night, put the front bumper and ACC camera back on without the lower fascia, and I drove home without incident or any pieces falling off.

[2180miles]

When we picked up on day 2, we were determined to finish the project before it got late again. It was around 16h00 by the time Rob got home from work and we got started, but we made solid progress as the sun made its way across the sky.

Now that the tow hooks had been figured out, we were able to move forward with tightening the entire Hidden Winch system down, and began the process of test-fitting the OEM Trailhawk bumper. In comparing it with the Limited / Overland / Laredo bumpers it seems that the grills is much more sloped back. I can’t comment specifically because I do not own any of the other models, but I do know that the guy who installed my clear bra on the WK2 made a comment about it being different from any other grille he’d ever seen. As such, Bill and his team were intrigued to know whether or not this system would work on the new model.

As we re-installed the bumper and fascia, we noticed that there were parts of the winch cradle that were pushing out against the both trim pieces, to the point where they would not fit back into place. We looked at our options for trimming the back side of each piece, and “modified” the bumper by bending the mounting tabs for the parking sensor looms upwards, essentially lightly breaking them to alleviate some rubbing on the winch cradle. The cradle is fit with 6 mounting points for the bolts that attach to the frame mount brackets, with each of those 6 points being U shaped, opening towards the front of the Jeep. Due to the space in the U-shapes, Rob and I decided to push the entire cradle backwards ½” or so to fit better behind the bumper and fascia. In talking to Bill at Chief, their 2015 model did not have room in front of the radiator to move back the way that we were able to in the 2017.

Once it was pushed back, we re-installed the bumper without issue, and popped the fascia back in as well. Knowing it would all fit, we turned our sights towards trimming out space for the fairlead to rest against the winch cradle mounting points. Initially, I was under the impression that this would be alike the other Rocky Road winch mount, with the fairlead being in the middle of the bumper by the license plate bracket. To my delight, it barely touched the bumper, and instead the majority of trimming came out of the fascia. I made a small cut, maybe ½” tall into the bottom most portion of the bumper itself, and then went to work tracing the fairlead to the fascia. When they have a final fairlead design, Chief will include a template for future installers to use when making their cuts.

Final Fascia Cuts & Removal by 2180miles

Once we were comfortable with the trimming, we moved on to the installation of the winch. The Zeon 10-S Platinum is described by Warn as being “built for those who push the limits-with double the durability, 20% faster line speed, and extreme IP68-rated waterproofing. The Advanced Wireless Remote controls not only the winch, but also the clutch and other accessories. With a 10,000 lb. pulling capacity, high-performance motor package, and Spydura® Synthetic Rope, you'll be equipped to go places others only dream about.” – for this application, it’s perfect, especially with the electrically controlled clutch. Whereas my other winch sits on the open front of my Wrangler, I don’t have access on the WK2 to engage and disengage the electric vs. free-spool setting. With the remote, this makes the hidden factor of the winch all that more feasible.

We followed Warn’s instructions for mounting the winch and spooling the Spydura line, outfitting the end of the synthetic rope with my new Factor55 Flatlink winch hook. Rated with a breaking point far beyond what I’ll ever be utilizing, the easy D-ring attachment point and red powdercoating make it a sleek addition to the front end of the Grand Cherokee. Once the line was appropriately attached we spooled it in, maintaining tension on the line by hand and wrapping it cleanly. While I don’t currently have any auxiliary lighting planned for the grille of the Trailhawk, the Zeon Platinum offers 2x 12v ports to plug auxiliary lights into, to then be controlled on/off by the wireless remote. I may someday add some lights in there, at which point this will be a phenomenal way to avoid running wiring through the firewall.

I took a couple dozen shots of the front end from every angle I could think of, and then we moved forward with re-installing the ACC camera on a Chief Products supplied bracket to the rear bolts holding the winch into the cradle. We had to wallow out the mounting bracket holes a little bit to fit what I assume is a revised camera mount dimensions, but notes and photographs were taken to show the guys at Chief.

Once the camera was good to go and re-harnessed, we re-installed the front bumper securing it back into the wheel wells and above the radiator by reversing the removal process. Putting the fascia back on we realized we had a little more trimming to do to get the outer edges by the wheels to fit appropriately. We got it to fit that night, but after driving last week with regular use, I realized I have to go back and re-trim some of the area in front of the fairlead mount to get the clips to sit properly back in the bumper above the fascia.

In the weeks - now months - after installing the Chief Products Hidden Winch system, I had no issues other than craning in my neck every time I turn around in the grocery store parking lot to check out the Jeep as I walk away. The pieces are secure, and the front end looks sexy as all get-out with the Factor55 FlatLink hinting that there’s a lot of pulling power under that front bumper.

I had an opportunity over Memorial Day Weekend to hook a tree-saver up to an Oak in my friend’s driveway and pull the WK2 uphill. While it wasn’t a stressful situation, the system, comprised of the mounting bracket, winch, hook, and remote performed flawlessly. I will go forward feeling more confident in the Jeep’s capabilities with this new self-recovery capacity in place. I still have some more trimming to do, but here are the photos taken in the days after we finished the installation. I’ll be sure to report back with notes from Bill and the great team at Chief, and will be sure to photograph the first opportunity I get to really put some stress on the system in a self-recovery scenario… not that I’m looking forward to that or anything ;-)

More photos to come in a less urban environment, but these will have to suffice for now.
