      Enhanced Street and Trail Performance. Drive your Wrangler to the rugged terrains with assurance and confidence that it can crawl with optimum stability. This Teraflex 4.50-Inch Alpine CT4 Long Arm Suspension Lift Kit is built for the rough off-roaders looking for optimum trail performance with street stability. It comes with a set of progressive rate coil springs, control arms, sway bar links, and track bar and bracket kit.

      Tough and Black Coil Springs. Teraflex engineered the progressive dual-rate coil springs through an intensive manufacturing process to incorporate optimum ratings and design. These are particularly built to reduce fatigue in the steel, eliminate sagging, and guarantee a consistent ride height. Each coil spring exhibits superior tensile strength to provide the necessary suspension support. Moreover, it is fortified by a black powder-coated finish for long-lasting corrosion resistance and extra durability.

      High-Quality Bars with Efficient Design. The front HD forged adjustable track bar improves steering response, center axles to optimize vehicle roll center, and reduce body roll for enhanced handling. This lift kit also features adjustable Alpine long control arms and brackets. These components balance the front caster and pinion angles. This kit also optimizes the rear pinion angle and tunes anti-squat geometry for proper suspension alignment. Additionally, these components facilitate smoother and quieter motion, thanks to the premium factory-style bushings.

      Dependable Sway Bar Links. Teraflex includes premium-quality rear sway bar links and front quick-disconnect sway bar links to enhance your Jeep’s handling by improving the balance and traction. Each bar exhibits excellent strength and high structural integrity to handle your JL’s off-road demands. The longer configurations of these sway bar links offer optimum clearance and maintain stability, especially during fast cornering or when treading through highly irregular terrains.

      Professional Installation Recommended. To ensure safety and optimum results, mechanical expertise is required in the installation of this 4.50-Inch Alpine CT4 Long Arm Suspension Lift Kit. It comes with all the hardware necessary to complete the installation process. This kit also requires aftermarket wheels with 4.75-inch backspacing or less – or offset wheel adapters.

      Includes a Lifetime Guarantee. A limited lifetime warranty is offered by Teraflex for this Alpine CT4 Long Arm Suspension Lift Kit that covers factory defects in materials or workmanship. Some exclusions may apply; please check the terms and conditions for 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 2021 2.0L or 3.6L Jeep Wrangler JL 2-Door models.

      Application Note. Using this kit on Jeep models with plastic bumpers would require the removal of bumper-to-fender wind deflector or splash guards to accommodate 35-inch or larger tires. The provided bump stop strike pad shim kit will be needed when using 37-inch tires on Rubicon models. It also requires longer shocks, preferably the Falcon Performance Shocks.
