The ultra-simple TeraFlex JL 4 Door 3.5 inch Coil Spring Base Lift Kit w/ 9550 VSS Twin-Tube Shocks includes just the basic lift components only and doesn’t have the drivability of a full suspension system. Requires front control arm Sport Brackets, or longer front lower control arms, or adjustable control arms, and/or an adjustable front track bar to correct suspension geometry.
We recommend Falcon Performance SP2 Mode Adjust Shocks or TeraFlex 9550 VSS Twin-Tube Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil springs to improve both compression and rebound for optimal vehicle stability. 3.5 inch Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.
