Part Number: 69-30300

• Lift your truck 3" in the front & 1" in the Rear 
• SST lift-specific Forged Torsion Keys
• Front inner fender bracket to fit larger tires
• Allows for no-trim 20x9 0 offset on a 35x12.50 tire

Includes:

• Right & Left front fender bracket
• Fender bracket hardware
• 1" rear block kit
• 1" U-Bolt kit
• x4 - laser cut washers
• 1/2" Differential drop spacer
• x2 - Torsion keys

Recommended 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 may be required depending on the 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 over lift 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 with trimming: 20x10 -18 offset - 35x12.50.  Some fender well trim variances may be experienced between the Silverado and Sierra models.
