Hello all, I got in to overlanding about a year ago but didn't have a vehicle that I was confident would break out from under me or tear itself apart in adverse conditions. At the time I had a 2007 Sierra SLT, I got stationed at Fort Carson, CO. about 6 months ago and didn't think that truck would hold up to the Colorado terrain or weather. Being a die hard General Motors fan boy having been raised in the company and working for them for 7 years prior to the Army I went with the most reliable vehicle in my opinion that GM makes. The 3/4 ton Duramax series of pickups. I got a 2011 Silverado 2500HD LTZ with an LML. Yes, it's a 7,800lb long wheel base vehicle. I understand it has it's limitations because of their size and weight, but they're my favorite vehicles on the planet. With that aside, I bought it bone stock on purpose because I didn't want to take on someone else's project. When I got it, it had 125,000 miles on it. It has BFGoodrich TA/K02's on it that are pretty new. After I got it I drove it from Fort Carson to my hometown in North Carolina outside Lexington and back as well as all across the state. I put about 4000 miles on it in 10 days, it showed be that I can rely on the truck. Since then I have taken in on some trails around Colorado Springs and Pueblo. The first thing I did when I got the truck was replace the audio in the truck, swapping the BOSE system for Kicker KS speakers, a new amp and a Kicker 10 inch sub, I also added a tool box. So, going on the trails around here I have noticed a need for more clearance. So in my research I have come up that I want to go with a BDS lift, however I'm having trouble deciding on exactly what kit/height to go with. On one hand lifting it too high would necessitate the use of a drop hitch, but at the same time if I don't do enough I run the risk of having terrain that's going to be a challenge because of clearance. So, I'm hoping y'all can help me out a bit, what are your thoughts on the subject? I'm probably either going to run Fuel Vapor wheels or Micky Thompson Sidebiter II's with the BFGoodrich TA K02's. I understand that BDS is expensive and that there are similar kit's on the market, however having worked with their warranty when I was a service writer and how extensive the warranty is and my techs constantly talking about how nice their components were I'm pretty adamant about either them as my kit. Also I wanted to know if I decided to go with the 3inch coilover if I would have enough suspension travel and ground clearance as opposed to something like the 4.5 inch regular kit.

Ill say that for my colorado duramax with 3 inch lift and 32' tires ive found i need a drop hitch when hauling a trailer, if your only going 3" id recommend just doing a leveling kit they are cheap and if you dont like it you can go to stock or upgrade to a real lift. Between 3" and 4.5" lift your really not going to notice much difference now go to 6" and youll notice. 20190323_111617.jpg

No experience with your gen but do have experience with the lb7 1st Gen. I used to have an 01 cclb with a 6 inch customized rcd lift with custom king shocks. @DieselPoweredCamel has an 02 ccsb with about a 3 inch lift ( we have no clue what it is as it came on the truck but looks like a combo of keys and different torsion bars). When we would go out when I still had that truck we were pretty well matched. Even tho I had a higher lift the front diff drop really didn't help front end clearance and the higher center of gravity didn't help much either. At the time I was running 35s and he was running 33s and has since switched to 35s. Imho if I were to do one of those trucks again I would go with a good 3 inch lift ( probably bds) and a set of good shocks, valved to the truck and driving style, and call it a day. While the 6 inch looked good there really wasn't much gained and the extra effort it caused in day to day was not worth the extra lift.

There is over 12 inch of clearance between the axles and the ground with 32s, my front bumper is 20 inches from the ground. My z71 colorado is 1.5 inches taller than the zr2 bison and has 1inch bigger tires. So far i havent gotten hung up on any rocks or logs or anything else. Lets say i do alot of blind water crossings and im not worried about hitting anything i drive over

Hi John!
Nothing wrong with a pick up, I own a 2016 Canyon Duramax with long box.
i have KO2's on it and a 2'' lift (leveling kit) It is a minimal set up but i dont rock crawl or go in mud pits!!
it is to get me to camping spots using forrest roads and some mild trails.
I have looked at countless scenarios for my rig and it always comes back to what I want to do with the vehicle.
Its my daily driver for works as well so cant go full out as it needs to remain street legal.

BDS is a solid company that offers good value and service, you would not be disapointed with it.
3 inch lift would be a minimum, higher depends on what you want to tackle.
coil over are much more comfortable than leaf springs, i would suggest you speak with BDS and tell them exactly what you want to do, they know their stuff and should find you the best set-up for what you want to do.

The nice thing about those 2500 is they already have a tall stance. A pro an con for some is the 3/4 ton gm has a independent front end. So leveling it will bring the front up how ever many inches a leveling kit levels it. The lifts really just allow you to get bigger tires under it and flex with out a rub.. your tires bring that pumpkin up and your lift brings your frame up. I put a 3 inch on my 1500 ram and ran 33.9 inch tires. And it sat prefect and for a full size rig. It handled every trail I wanted it to go on.


I live in northern colorado and the trails around here get kinda narrow. But a full size pickup is the way i went because of pulling horses with it. Exactly why I didnt go all out because it still needed to pull a trailer with out a big ass extension for a hitch

Yeah, I sent them an email asking about it to see what they think. I appreciate the help. Any good places in Northern CO that you can reccomend?

My bad, responded to the wrong person.
I do alot with bullhide 4x4 and fort collins 4x4. Both in Fort Collins. The bullhide place does very good work with heavy duty pickups. I had them do a ton of stuff with a ram 5500 i had and was pleased. If you like working on your stuff you can get parts pretty quick. Or they install but they have a big waiting list.

4wheel parts is less than a mile or two from the house but like dealing with the local guys

I meant more so along the lines of good trails and places to ride go around there. But I do appreciate the shops, I'll keep them in mind!

Oh i gotcha there. There are alot west of loveland fort collins. 7mile and old flowers road ballard road. Are ones that arent to bad for a stock pickup. Green ridge is good for a built one if its a short box it can move around ok. Killpecker and sandcreek roads are both fun If you look at maps for red feather lakes. Pingree park. Seven mile creek. Storm mountain west of loveland. Think that one comes out as drake colorado but not sure. There are some back toward lyons co west and black hawk. But cant remember the names.

@old_man probably knows more of the names than I do that are west of lyons. Cant remember the name of it but one goes up to an old military plane crash. That one was a bit tight for me
You mean where you turn off of Peak to Peak highway and go up towards Middle St. Vrain and take Bunce School road?

Middle St. Vrain is nice with the campgrounds at Camp Dick and Peaceful Valley. If you keep going up, you can take the trail south over to Coney Flats, but it is a bit rough (he...he)

Boulder, CO 80301
(303)541-2500
Summary:The Middle St. Vrain River flows out of the Indian Peaks Wilderness along the Continental Divide and is the focal point for this muli-use area. Once a logging road to a mill and the surrounding timber supply, the old road is now used for motorized recreation and as access to an Indian Peaks Wilderness trailhead.
Attractions:At mile 3 along the Middle St. Vrain 4WD road is the Timberline Falls. Though the falls are not visible from the road, they are a 0.1 mile walk from the road. There is no trail, so you will have to find your way. There is a sign along the road marking the location of the falls (signs may be vandalized and not present). The Middle St. Vrain 4WD Road connects with the Coney Creek 4WD Road via the Coney Creek Cutoff.
Seasonal
Closure:
November to Late JuneThe Middle St. Vrain seasonal closure gates do not open until late June, or the first part of July. The 4WD road is reviewed as early as the third weekend in June by the Trailridge Runners 4WD Club to determine if the snow drifts have melted and the road bed is dry enough to handle vehicle traffic.
Best Time:July - Early in the month water crossings will be deepest due to spring run off. (All crossings are hardend to eliminate environmental impact)
August - Busiest time for all activities.
September - Late month for fall colors. Good views of Sawtooth Mountain and the Continental Divide.

Yes bunce school road is the name! I havent been up in that area in a long time. Poll hill road is nother good one. Another way to get to estes park. Pretty open for a full size.
Pole hill is normally closed with a locked gate so good luck. Used to do that a lot a few years back.
