• SST lift-specific Forged Torsion Keys
• Front and rear Falcon 1.1 Monotube series shocks
• Xtreme-Duty fabricated 4130 chromoly steel Upper Control Arms
• Front inner fender bracket to increase larger tire clearance

Tire Fitment:

• 20x9 0 offset - 35x12.50 tire
• *Max with trimming: 20x10 -18 offset - 35x12.50

• Silverado and Sierra have different fender well opening sizes - some minor trimming my be required depending on true tire size and design. Max width on stock wheels is 11.5"
•  When setting the torsion key adjustment bolt do not exceed 27” from the wheel center to the fender edge. Exceeding this will overlift the vehicle creating a top-off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components.  Max width on stock wheels is 11.5".
