The TeraFlex JL 2dr Sport/Sahara: 2.5" Performance Spacer Lift Kit w/ Shock Extensions is the most economical way to fit larger tires and increase ground clearance on your JL Wrangler Sport or Sahara with the least amount of modifications. We recommend Falcon Performance SP2 Mode Adjust Shocks or TeraFlex 9550 VSS Twin-Tube Shocks. These are the only shock absorbers engineered to work with TeraFlex lift coil spring spacers to improve both compression and rebound for optimal vehicle stability. 2.5" Performance Spacer Lift Kits are offered with TeraFlex 9550 VSS Twin-Tube Shocks with shock extensions or without shock absorbers or extensions. Falcon Performance Shocks are available separately.
