The TeraFlex 4" 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" Coil Spring Base Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks or without shock absorbers. Falcon Performance Shocks are available separately.

WARNING: This product can expose you to chemicals including Di(2-ethylhexyl)phthalate (DEHP), which is known to the State of California to cause cancer, and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov/product
