We include CNC’d aluminum differential spacers and Hardened 10.9-grade fasteners to ensure your front drive axles maintain proper driveline 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 overextended. 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 loses 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 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.

Product Reviews

This is the 2nd kit I've bought from Suspension Maxx. 1st was on my 2015 GMD 2500HD. This kit went on my 2020 GMC 3500HD and was the only kit I even considered. Installation was painless with both the instructions and the video to help guide. Looks and rides amazing and keep getting compliments every where I go. Another amazing product from Suspension Maxx!!!
