The TeraFlex JK 4dr: 3"" Coil Spring Lift Kit w/ Track Bar includes just the basic lift components only and doesn’t have the drivability of a full suspension system. Requires longer preset or adjustable control arms to correct suspension geometry.
Does NOT include shocks. We recommend Falcon Performance 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. Shocks are available separately.
