Pro Comps Level Lift Torsion Keys are the fastest, safest, least expensive way to bring the front of your Vehicle level with the rear. This gives you the clearance and ability to add wheels and tires up to 33" in dia. Pro Comp products do not affect the factory OEM ride quality or comfort. That's why Pro Comp also offers a lifetime warranty for as long as you own your vehicle against defects for all of our products.
Overall fantastic bang for your buck. It changed my truck. I bought my truck new GMC 2500 Denali and the rake on it was silly looking. 2.5" and some 285/65 r20 BF Groodrich AT KO2s and what a difference. It's a show stopper. I kept the factory wheels so it looks clean and classy. I've heard complaints that it's not exactly level. True it's 1" different but 1" over a truck that big is lottery unnoticeable. I was worried it would look the same cause the guys a four wheel parts just didn't want to steer me one way or another but let me help. You'll be very happy with this. Lastly the ride. Little stiffer then the factory ride. Not terrible. Definitely noticeable on speed bumps. Recovery is poor. How that translates off road I have no clue.

I had this product installed by 4Wheel Parts on my 2011 Silverado 2500 HD Z71 Crew Cab and have been extremely pleased with the results. I was very pleasantly surprised that the vehicle rides just as smoothly as it did with stock keys; it is not stiffer at all! I was a little disappointed that the vehicle still had about an inch of rake after installation so, since I rarely haul anything extremely heavy, I removed the overload springs, which leveled the truck perfectly. I could not be more pleased with the Pro Comp leveling kit, and absolutely love the new stance of my truck. Now, without the huge rake, my truck looks and sits like the 4 Wheel Drive truck that it is. I highly recommend this product.

Installed on my daily driver, 2012 GMC 2500HD with XD cranks and 305's on 18's. Gave plenty of clearance and turning ability.Slightly stiffer ride but worth it!

I installed these on my 2011 2500 HD. It does ride a little stiff, but greatly improved the conrnering ability. The look is perfect. Not exactly level, but level enough.(rear end up about .5 to 1 inch)Can't wait to put bigger wheels and tires on.

Retains OEM ride quality...not exactly!
Installed this on my new 2011 Sierra 2500HD. Ride is much stiffer than anticipated based on their claim that OEM ride quality is maintained. Cracks and holes in the road feel real exaggerated in the front in and seem to make more bumping noise than stock. I just went up one size tire, I may put the stock keys back in and screw them down a little to fit. Should get the same result in ride.
