JT 3.0 Inch Pro-X "No Limits" Coil Over System

Write a Review

The Rock Krawler JT 3.0 Pro-X Coil Over ”No Limits” System was specifically designed for Rubicon owners who want to retain their factory electronic sway bar disconnect feature. The No Limits kits also offer 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. (Also, available for Dana UD60 and Dynatrac XD60 Applications)

*If building an overland or heavily upfitted build in the back, we recommend upsizing 1” in coil lift height for the rear.

*For tires larger than 37" or hard core off-road use, welding of the rear cradle to the axle tubes is required.
