The ultra-simple TeraFlex JT: 2.5in Coil Spring & Spacer Base Lift Kit comes with the basic parts needed to fit larger tires for increased ground clearance for better off-road capability. Does NOT include shocks. We recommend Falcon Performance Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil spring spacers to improve both compression and rebound for optimal vehicle stability. 2.5in Coil Spring & Spacer Base Lift Kits are offered without shock absorbers. Falcon Performance Shocks are available separately.
