Hi
@mtn_matt ! I'm also a 2016 JKU. There's a number of setups you could go with, and it really depends on how much weight you're carrying around, and ultimately how much you want to spend. I ran the ARB Old Man Emu Extra Heavy Duty springs with the Old Man Emu shocks for awhile. I quickly realized the Old Man Emu setup was actually just a bit too soft, especially for my liking, especially when fully weighted. I'm also daily driving my Jeep on the highway and I was not happy with the way that setup felt with highway driving and carrying the weight.
If you really look around, you'll find the Teraflex Outback Springs that
@MazeVX mentioned to be one of the most popular spring set ups. Most are also running those with the Falcon shocks as well, available in a non adjustable shock, and also in the 3.3 adjustable's. The adjustable Falcons have a wide range of adjustability, from full soft when you aren't carrying the extra weight, to a much firmer setting that is a night and day difference. There's also 9 other adjustments in the middle range to fine tune.
I've also run some other spring setups, including AEV, and Bilstein shocks as well. I personally feel the Teraflex and Falcon Adjustable's(running that myself) is the better setup for what we do. As I said, mine's a daily driver, and I average over 20k a year driving back and forth to work, and getting out almost every weekend on a trip. I'm almost always fully loaded as well, ready to head out at any notice. I'm completely happy with the TF and Falcon setup, and highly recommend it. Consider the Hellwig rear sway bar as well, along with some polyurethane front sway bar bushings. Those also help, although to a smaller degree, with handling, entrance and exit ramps, etc by keeping the body roll down a bit.
