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.

The parts look like they'll last forever, but I can't really tell it's installed! My truck isn't level, that's for sure. I used the recommended tire size and ensured the kit was right for my truck. I get grinding from the tires hitting the liner, and the liners are in proper condition.

I installed this on my 06 Chevy Silverado and I love the way it looks. I raised the front just a little higher than the back because I like the way that stance looks. I would highly recommend finding the torsion key tool if you are going to install yourself. I used a c-clamp and it took about 1 hour and 1/2. But with that tool, it could easily be done in 20 to 30 minutes.

Perfect form my application
I wanted to eliminate the forward rake that my '02 Avalanche had, and this ProComp leveling kit did just that. It looks right, and handles much better now. Previously, I was also looking to stiffen up the suspension by changing the shocks. I hoped to make my truck feel more like a truck and less like a Caddy. That issue was resolved as well after the kit was installed. 4WP did the install and alignment, everything checked out. They did a great job. Thanks.

Easy ordering process and great prices
Looks great. 33" is the limit on tire size and it would be better to go a hair less.

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!
By Machine Gun Clay from Ft Worth, Texas
Installed on my 02 Avalanche. Got it installed locally for $60. Leveled the truck perfectly and looks great. Can't wait to get bigger tires. A+
What size shocks are needed for this leveling kit installed? Is a change in steering stabilizer or control arm needed for this torsion key leveling kit modification with 33x12.50s installed?

Hi, I have a 2001 GMC Sierra 2500HD with an LB7 Duramax engine. First question is will these be able to handle the weight of a diesel engine? Second question, will they affect towing capabilities at all? And third question, do you think I could fit 285/70r17 tires mounted on wheels with 4.5 inch backspacing without rubbing anything?
Idaho Redneck from Nellis AFB, NV on
Helo Idaho Redneck,
Yes, this will handle the weight of the Duramax engine. No, this will not effect towing capabilities at all. Ye, you can fit a 285/70r17 tire without rubbing. Thank you for the question.
RK from Nellis AFB, NV on
If I change out my torsion keys will I need to get different front shocks, and will I need an alignment. Thank you
Bryan from Fayetteville NC on
Yes, you will need longer shocks and need to have the vehicle aligned. Thank you for the question.
