This easy to install system elevates the new JL’s ride quality and off-road performance. Coil spring rates are perfectly tuned for bump compliance and load handling and are complemented by 2.5" diameter floating piston monotube shocks. These shocks are precisely tuned by Rubicon Express to maximize all terrain comfort, overall driver control and stability. Detail features include 1.75" diameter 4130 chromoly Super-Ride front lower arms, extended sway bar end links and extended bump stops to boost off-road capability. This highly tuned system will provide the right height to clear 35" tires on a loaded non-Rubicon models and 37" tires on Rubicon models.
