Designed to improve stance, performance, and capability, this kit includes everything necessary to clear up to 35" tires and features bolt on Falcon 1.1 Monotubes shocks designed specifically for your Duramax to increase travel and the ability to navigate rough terrain and smooth out on-road comfort.

Part Number: 69-30320

  •  3" Front/ 1" Rear SST Lift Kit
  • 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".
