The TeraFlex JT: 2.5in RT 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/or adjustable front track bar to correct suspension geometry as well as other components. 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. Complete Alpine RT Suspension Systems are offered with select Falcon Piggyback Shocks including: 3.5 aDAPT e-Adjust, 3.3 Fast Adjust, or without shock absorbers. Other Falcon shocks are available separately.
