Description
The Rock Krawler JT 4.5 Pro-X "No Limits" System was specifically designed for Rubicon owners who want a complete bolt-in installation, maximum articulation from a mid-arm kit and the durability and off-road performance you expect from Rock Krawler Suspension. The "No Limits" front sway bar links allow Rubicon owners to use the factory sway bar disconnect function and still achieve maximum articulation. The triangulated 4 link rear assembly maintains the rear axle perfectly centered; allows for removal of the rear track bar, eliminates rear suspension bind, and the cross talk of the front and rear track bar arrangement greatly smoothing the highway ride. The X Factor Series adjustable lower control arms offer a total of 90 degrees of misalignment. The Triple Rate front coils paired with our Quad rate rears coils provide unmatched ride quality and off-road performance, while maintaining standard JT rear load capacities. The Rock Krawler Pro-X Gladiator Mid Arm System is the pinnacle of bolt in suspension for the JT platform.
