Product Details

Superlift’s 6 Inch Lift kit for the 2020-2023 Silverado and Sierra 2500HD and 3500 HD utilizes a “NO DROP” Torsion Bar relocation bracket that keeps the torsion bar crossmember raised up and in the stock location.

This design maximizes ground clearance at the frame for a clean look and prevents damaging the torsion bar assembly while off-roading. Precision CNC Machines Steering Knuckles and heavy duty lower control arm crossmembers insure your Silverado or Sierra will have and maintain perfect alignment specifications. 

This Kit features the following Shock options: Shadow Shocks or Front and Rear Bilstein 5100 Series Shocks. 

The rear lift is achieved with a heavy duty fabricated rear block. The primary axle u-bolts are captured in the upper and lower plates with the secondary u-bolts attached to the OE leaf Spring to reduce pinion wrap. Fully functional, axle mounted, compression stop system prevents over compression.  

This kit includes steering knuckles, crossmembers, torsion bar brackets, front sway bar links, belly pan, brake line brackets, bump stops, rear block kit and shocks.  All required parts are included to make sure your Silverado or Sierra handles and performs just like a stock truck!

Superlift’s 6-inch 2020-2023 GM 2500|3500 HD UCA Lift kit is an installer friendly and is backed by a lifetime warranty and Lift Force supplemental powertrain warranty.
