The ultra-simple TeraFlex JL 4dr: 2.5" Coil Spring Base Lift Kit w/ 9550 VSS Twin-Tube Shocks comes with the basic parts needed to fit larger tires for increased ground clearance for better off-road capability without compromising on road handling.
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. 2.5" Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.
