      True Cross-Trail Experience. Take your Jeep Wrangler JL to the rugged terrains with the assurance that it can successfully scale the obstacles with confidence. This Teraflex 4.50-Inch Alpine CT4 Long Arm Suspension Lift Kit delivers cross-trail performance with factory ride quality. It also allows the installation of larger tires and wheels for improved ground clearance and a more aggressive off-roading capacity.

      Comfortable Ride. Teraflex engineered the heavy-duty coil springs in this kit with extensive rate tuning and dynamic balance. Linear rate technology ensures the maximum number of active coils under load for consistent performance and predictable handling throughout the full range of suspension travel both on and off the road. Moreover, the springs’ high-tensile strength offers reliable suspension support.

      Alignment and Stability. This 4.50-Inch Alpine Suspension Lift Kit uses Alpine CT4 Long Control Arms and brackets. This control arm kit provides significant improvements in the overall steering and handling of your vehicle. This kit, together with the included adjustable HD track bar kit, also facilitates successful navigation on challenging trails with the enhanced steering capabilities.

      Professional Installation Recommended. Featuring bolt-on installation, this Alpine Suspension Lift Kit comes with all the necessary installation hardware. For optimum results, mechanical expertise is highly recommended in the installation.

      Limited Lifetime Warranty. Teraflex backs this Alpine CT4 Long Arm Suspension Lift Kit with a limited lifetime warranty against manufacturing defects in materials and workmanship. Please check the terms and conditions for exclusions and full details.

      Application. This Teraflex 4.50-Inch Alpine CT4 Long Arm Suspension Lift Kit is specifically designed to be used on all 2018 to 2023 2.0L or 3.6L Jeep Wrangler JL 4-Door models.

      Application Note. Removal of bumper-to-fender wind deflector or splash guards is required to accommodate 35-inch or larger tires on JL’s with plastic bumper. The provided Bump Stop Strike Pad Shim Kit will be needed when using 37-inch tires on Rubicon models. This kit also requires aftermarket wheels with 4.75-inch backspacing (or less) – or Offset Wheel Adapters for stock wheels.
