The TeraFlex JL 2dr: 4.5in Coil Spring Base Lift Kit includes just the basic lift components only and doesn’t have the drivability of a full suspension system. Requires front control arm Sport Frame Brackets, or adjustable control arms, and/or adjustable front track bar to correct suspension geometry. Does NOT include shocks. We recommend Falcon Performance SP2 Mode Adjust Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. 4.5in Coil Spring Base Lift Kits are offered without shock absorbers.
