The TeraFlex 4 Inch Coil Spring Base Lift Kit w/ Front Track Bar includes just the basic lift components only and doesn't have the drivability of a full suspension system.

Requires adjustable short or long Alpine (IR) Control Arms and/or Rear HD Forged Adjustable Track Bar to correct suspension geometry.

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 Inch Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.
