The TeraFlex JL 4dr: 2.5in ST2/CT2 Coil Spring Base Lift Kit 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 and adjustable front track bar to correct suspension geometry. Does NOT include shocks. We recommend Falcon Performance 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. Complete Sport ST2 and Alpine CT2 Suspension Systems are offered with select Falcon Piggyback Shocks including: 3.3 Fast Adjust, 3.1 Piggyback, 2.1 Monotube (ST2 only) or without shock absorbers. Other Falcon shocks are available separately.
