Hi All, finally picked up my truck today from the shop and really happy with the aftermarket selections. I have a few more to go, but wanted to provide some parts if anyone looking at similar mods in the future. Truck started with 2.25” rake and now measures 41” front and 41.5” in rear. Very happy with the stance with having still the 1/2” rake.
Front:
- Zone Off Road new UCA that is made for their 1.75” leveling kit. The shop owner feels these are the best that are reasonably priced and after feeling them, I believe him. Very heavy duty and also look great. The link below shows the whole kit, but you can buy just the UCA for $600.

- 2” spacer kit from Body Armor 4x4. This is a top spacer that provides the lift. Not AT4X specific but the shop had used these on a couple Silverado ZR2 with same DSSV set up and worked very well. Aligned and drives great, more to come after a few miles on the truck.

The AT4X has the DSSV shocks, so keeping those of course. Didn’t touch the rear suspension as my truck had a 2.25” rake before level.
Tires I went with the new Toyo RT Trail in a 295/60r20. (33.9x11.8) supposed to be very quiet on road and only 62 lbs which is great for a LT tire in this size. First 50 miles driving I would say they are equivalent to the Nitto Recon Grappler, which are just a little quieter than the Ridge Grappler.

Wheels are Fuel Blitz 20x9 +1 offset. I wanted the +20 but the thinker UCA barely rubbed at full lock, so went with +1 to give me clearance and a more aggressive stance. Wheels came with black/chrome caps, so switched to the all black Fuel center caps. Def worth the $50/set of 4!
- Back Flip tonneau cover
- GM Parts for blacked out AT4X badging and 6.2L side fender badges. Still need to replace front grill red/chrome, but black was out of stock and didn’t want the chrome surround. PS the illuminated GMC badge GMC sells doesn’t fit the new grill with AEV bumper, nor does the AT4X tiny badge on lower driver side of grill. Will paint myself later I guess.
- Front windows tinted to match the rear
Thanks and hope this helps!

The Open Country R/T Trail is an On/Off-Road Rugged Terrain Tire.
The Open Country R/T Trail rugged terrain tire delivers better off-road grip than a traditional all-terrain tire, most evident in sand, mud, and deep snow.
