The ultra-simple TeraFlex JT: 2.5in Performance Spacer Lift Kit is the most economical way to fit larger tires and increase ground clearance on your JT Gladiator with the least amount of modifications. Does NOT include shocks. We recommend Falcon Performance 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. 2.5in Performance Spacer Lift Kits are offered without shock absorbers. Falcon Performance Shocks are available separately.
