The TeraFlex JL 4-Door: 3.5” 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 Brackets, or adjustable control arms, and/or adjustable front track bar to correct suspension geometry.
Does NOT include shocks. We recommend Falcon Performance Shocks. Falcon shock absorbers and TeraFlex lift coil springs have been engineered together to improve both compression and rebound for optimal vehicle stability. 3.5” Coil Spring Base Lift Kits are offered without shock absorbers. Falcon Performance Shocks are available separately.
