- Complete 4-Corner Shock Package
- Provides a True 2” Front Level
- Forged Torsion Keys
- Includes Inner Fender Brackets
- Bolt-On Installation
- FITMENT & TIRE CLEARANCE
- Allows fitment for:
- 20x9 wheels with +18 or 0 mm offset
- Up to 35x12.50 tires*
- *Trimming may be required with certain tire designs when using 20x9 wheels with 0 mm offset and 35x12.50 or 326/60R20 tires.
- Special Note: When setting the torsion key adjustment bolt do not exceed 26" 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.
