We offer the most complete leveling kit available for your Chevy Silverado 2500HD, 3500HD & GMC Sierra 2500HD, 3500HD trucks.  Using the highest quality American Made parts that will ensure your truck stands the test of time. We back our leveling kits with our MAXX structural lifetime warranty.  The SuspensionMAXX  maxx cam 3 torsion bar key is manufactured form 4140 investment cast, heat treated American made Steel! We include CNC’d aluminum differential spacers and Hardened 10.9 grade fasteners to ensure your front drive axles maintain proper drive line angles. Every component down to our shock extensions are precision machined, zinc coated. We include these extensions with our kit ensuring your shocks are not over extended. Longer shock studs are included to allow you to fasten your factory wire harness in place. Last but not least, the MAXX travel control arms, designed to give you increased ride height while maintaining proper suspension geometry and travel. Some may ask why changing the control arms are necessary. We have designed our control arms to compliment the leveled ride height. The factory control arms are flat across all three mounting points and as you lift your truck, the ball joint angle is increased.  At the same time the upper control arm looses clearance to the suspension limiting bump stop that is located under the front of the upper A-arm.  Our hand fabricated, TIG welded control arms feature improved clearance to this bump stop. The MAXX travel what will allow you to lift your truck up to 3” from stock while maintaining a satisfactory ride.  Our control arms are had fabricated from 0.188 wall 1-3/4” tubing, powder coated finish and utilize greaseable MOOG ball joints for trouble free operation for thousands of miles.  If you desire the best kit for your HD Silverado or Sierra and you value quality American made craftsmanship, look no further than SuspensionMAXX for the most complete 3 inch leveling kit on the market.

SuspensionMAXX stage 2 3" leveling system for your 2011-2019 GM HD trucks Includes Fox 2.0 shocks

Stock control arms are designed around the factory ride height. The factory arms are designed to limit out or hit on the upper control arm bump stops a 2.5" Which will severely reduce the ride quality and drastically reduce ball joint life. Changing the upper control arms to the maxx travel arms will allow for increased suspension travel and improved ball joint angles at leveled ride heights.

Shock spacers are not used with the FOX 2.0 front shocks.


We do offer the block and U-bolt kits, but they are sold separately.

Yes, the Burgandy GMC Sierra Denali has 35/12.50/20 Toyo Open Country At3s.


Suspension Maxx leveling kits do not change the track width of the front suspension.

Product Reviews

I put the Stage 2 leveling kit with Fox shocks in my 2018 Chevy 2500, it looks great and rides so much better, I'm very happy with it. Also, I had purchased the steering stabilizer and installed it well before this went in, but then did the Cognito PISK when the level was done and I unfortunately had the wrong bracket to work with it (my fault, not theirs), so they worked with me to get the correct bracket. All of it was extremely fast to ship and great customer service. I would highly recommend working with them!
This kit is awesome just put it on my 2019 2500 Duramax with the steering stabilizer. Rides very nice. I was able to put 20x10s with a 305/55R20 tire. We had to do some trimming but it turned out awesome.
Great lift and made in USA.made a world of difference in appearance of truck and still rides like it’s from factory.Upgraded to FOX shock package with my kit.
Great products all around Made right here in the USA, I have a 2017 GMC Sierra 2500HD 4 x 4 Diesel, I live in Tennessee and drove to Suspension Maxx in Bay City, Mi to have them install the level kit, Fox shocks and highly recommend the steering stabilizer kit as well, I met the team great group of people who do outstanding work, I purchased the Stage 2 Fox Shocks 3
Solid product. Love the way my truck looks and get tons of compliments for such a low key upgrade. I’m running a 2018 GMC 2500 on 35x12.5x20 Toyo Open Country AT3’s on stock rims. Upgraded to Fox shocks after the install. There’s a bit of rub with the stock rims. Doesn’t ride all that different after install except the front articulates better and feels a little floaty. Fox shocks don’t affect the ride so much (2500 suspension is stiff) but do help with roll/sway a lot. Totally worth it. Do yourself a favor and get the steering stabilizer kit as well. Really helps with tracking and ride quality.
Recomendado al 100%
