TeraFlex Coil Spring Base Lift Kits raise your Jeep for more off-road ground clearance. These kits require additional components to correct suspension geometry — sold separately.
TeraFlex 4.5” Coil Spring Base Lift Kits include just the basic lift components only and do not have the drivability of a full suspension system. Requires Front Control Arm Sport Brackets or adjustable short or long Alpine (IR) Control Arms, and Front and/or Rear HD Forged Adjustable Track Bar(s) 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. 4.5” Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.
