The TeraFlex JK 2dr: 4" Coil Spring Base Lift Kit includes just the basic lift components only and doesn–t have the drivability of a full suspension system. Requires adjustable control arms and adjustable front track bar to correct suspension geometry. An adjustable rear track bar is recommended. Does NOT include shocks. We recommend Falcon Performance Shocks or TeraFlex 9550 VSS Shocks.
