Description
The JT 4.5 Silverback "No Limits" suspension systems bring together the advantages of a full high clearance 4 link long arm front suspension with a triangulated 4 link rear assembly. The "No Limits" front sway bar links allow Rubicon owners to use the factory sway bar disconnect function and still achieve maximum articulation. This setup keeps the rear axle perfectly centered throughout the suspension cycle; 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.
