Alpine CT4 Long-Arm 4.5-Inch Suspension Kit for Jeep Wrangler JL Unlimited 4-Door (2018+), No Shocks

The Alpine CT4 long-arm 4.5-inch lift kit is a complete high-performance suspension system created for enthusiasts who want maximum capability, full geometry adjustment, exceptional articulation and reliability in the harshest off-road conditions.

Thanks to the Alpine IR adjustable long arms and purpose-designed mounting brackets, the system delivers significantly better suspension performance than standard solutions. The independently rotating bushings allow the axles to move freely, reduce vibration and provide an exceptionally smooth and quiet ride.
