JLU 3.5 Inch Coil Spring Base Lift Kit and 9550 VSS Twin-Tube Shocks For 19-Current Jeep JL Wrangler Unlimited 4 Door TeraFlex
The ultra-simple TeraFlex JL 4dr: 3.5 inch Coil Spring Base Lift Kit with 9550 VSS Twin-Tube Shocks 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 longer front lower control arms, or adjustable control arms, and/or an adjustable front track bar to correct suspension geometry.
We recommend Falcon Performance Shocks or TeraFlex 9550 VSS 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.
Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon SP2 Mode Adjust Performance Shocks are available separately.
