      Aggressive All-Terrain Performance. Upgrade your JL’s suspension system for improved off-roading capacity by installing this Teraflex 4.50-Inch Alpine CT4 Long Arm Suspension Lift Kit with Falcon SP2 3.1 Piggyback Shocks. This lift system accommodates up to 37-inch tires and provides an aggressive, lifted, and level stance with superb ride quality. It also comes with well-engineered components such as Alpine long control arms, Falcon shocks, adjustable track bar, coil springs, and bump stops.

      Smooth and Stable Ride Quality. The Falcon SP2 3.3 Piggyback Shocks in this kit are furnished with Volume Optimized Damping (VOD). This features a digressive linear valve to improve vehicle feedback, stability, and control during low-speed, high-speed, and off-road driving. This valving maintains stability, comfort, and control throughout all driving conditions.

      Smooth and Comfortable Ride Quality. For the coil springs included in this kit, TeraFlex utilizes advanced technology to ensure a maximum number of active coils under load for consistent performance. This delivers improved handling throughout the full range of suspension travel for optimal vehicle stability. Additionally, these high-strength springs come covered in a black powder-coated finish for reinforced corrosion resistance and longer service life.

      Superior Handling and Alignment. Built for better precision control and steering stability, this suspension upgrade includes Alpine CT4 Long Arm Kit. These control arms were fabricated using heavy-duty drawn-over mandrel tubing with reliable weld integrity, superior strength, and excellent structural properties. Moreover, each control arm is furnished with premium bushings with improved load-bearing capacity. This entire set was particularly engineered to durably handle your Jeep’s all-terrain challenges.

      Professional Installation. This Alpine CT4 Long Arm Suspension Lift Kit includes all the necessary hardware for the installation. The bolt-on installation process completes with the mechanical expertise required.

      Carries a Lifetime Warranty. This Alpine CT3 Long Arm Suspension Lift Kit is backed by a limited lifetime warranty against factory defects in materials and workmanship. This warranty comes with exclusions; please check the full warranty policy for complete details.

      Application. This Teraflex 4.50-Inch Alpine CT4 Long Arm Suspension Lift Kit with Falcon SP2 3.1 Piggyback Shocks is intended for use on all 2018 to 2021 2.0L or 3.6L Jeep Wrangler JL 4-Door models.

      Application Note. Using this kit requires aftermarket wheels with 4.75-inch backspacing or less, or Offset Wheel Adapters for stock wheels. It also requires the removal of bumper-to-fender wind deflector or splash guards to accommodate 35-inch or larger tires on JL’s with plastic bumper. Moreover, the provided Bump Stop Strike Pad Shim Kit will be needed when using 37-inch tires on Rubicon models.
