PC21 1500

Overall, the kit was in-fact bolt on, just took me a long time to do it (I'm certain others can do it twice as fast). Ride quality is a huge improvement over stock. It is less bouncy and it soaks up pot holes and dips effectively. I am running the truck on level 2 of 8 in terms of stiffness, I would increase if I was going to be off road. Rugged Treks are very quiet, but I haven't been on the freeway yet. Very comfortable with the windows open around 50mph. Let me know if you have any questions while its still fresh in my mind.

After install I have 7.5" of clearance from tire to wheel well on the front, so the kit yielded 3.25" of lift up there. The rear went to just shy of 8.5" of clearance between tire and well, so I got just under 3" of lift in the rear with the 2 inch block and Vertex shocks. The truck has less than 1 inch of rake, which I don't mind at all due to all of the electronics reading the road. Also, after driving around and taking sharp turns in forward and reverse in full lock there is zero rubbing anywhere. (Even the stock tires would rub ever so slightly at full right turn on the wheel well liner.) I did no trimming or modifications of any kind.

More details, Front before lift had 4.25 " from tire to wheel well. Rear had 5.125" from tire to wheel well.

I've used this site a lot and I wanted to post some specs for the lift I did with approx cost. Links at the bottom. Ill post some pictures after the alignment with actual lift yield and say if I have any rubbing, on the drive over I did not. I have a 2021 GMC Sierra SLT 4WD with premium plus trim and X31 package. 6.2 engine, standard bed, crew cab. Rough Country 3.5 inch lift kit with Vertex shocks all around. 2399 + tax, free S/h, Minus military discount, Thanks for the support! (I did the install myself in my driveway, it took me forever, about 13 hours. Ended up using 3 different jacks for the rear, but could have gotten away with 1 if I had taller jack stands. You need to be able to support the frame with the rear suspension at full droop. I did the entire rear install with the wheels on so if a jack failed I would be safe. There are better ways, but that's what I ended up doing. The front was doable with regular stands and 1 jack.) OEM GM 18x8.5 wheels with 26mm offset (from ebay) link below. $775 + tax, free S/h, comes with OEM center caps. Seller was awesome, fast shipping and brand new GM products in their boxes and packaging from factory. Cooper Rugged Trek 275/70R18 tires from Discount Tire online, works out to be about 34 x 11. $294 a tire + tax, free shipping, Minus military discount, Thanks for the support!

I've painted many calipers, and from now on I'll get these if I can. https://www.roughcountry.com/gm-suspension-lift-kit-22630c.html?find=2021-gmc-sierra-1500-4wd-752716 https://www.ebay.com/itm/84641199-4-GM-18-Gloss-Black-OEM-Wheels-2007-2021-Silverado-Sierra-Tahoe-Yukon-/373602687357?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=711-127632-2357-0 https://www.discounttire.com/buy-tires/cooper-discoverer-rugged-trek https://www.calipercovers.com/ Local shop did mount and balance for 20 a tire.
