Superlift Suspension Systems now available with Fox® Shocks:

Superlift’s 6 Inch Lift kit for the 2011-2019 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 Fox® Performance Series 2.0 IFP shocks – Front and Rear.

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.

This kit includes steering knuckles, crossmembers, torsion bar brackets, front sway bar links, belly pan, brakeline brackets, bump stops, rear block kit and front and rear Fox® Performance 2.0 Shocks.  All required parts are included to make sure your Silverado or Sierra handles and performs just like a stock truck!

IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.
