For serious off-road use, step up to a JKS J-Konnect 2.5" suspension system for your Wrangler JK 4-Door. J-Konnect can tackle aggressive terrain including rocks and ruts without giving up street manners or breaking the bank. J-Konnect system takes suspension component strength and suspension geometry a step further by adding front and rear fixed-length J-Link lower control arms along with a drag link flip kit and track bar braces. In addition to being significantly stronger than factory control arms, J-LINK lower control arms add front caster and rear wheelbase. Built from 2" x .250-wall DOM tubing, J-LINK control arms provide street-friendly NVH isolation with large factory style rubber bushings at both ends. The drag link flip kit flattens the steering angle to mimic factory angles, while the track bar adds strength and protection. Combined with the matched dual-rate coil springs, and your choice of a selection of custom-valved FOX shocks, an adjustable track bar, Quicker Disconnect sway bar end links, and more. J-Konnect is ready for aggressive trail performance. Get connected with J-Konnect.

Picking the Right Coil Springs
JKS J-Rated Suspension Systems feature custom wound, progressive rate coil springs. That means the spring rate increases as the spring is compressed. You and your Jeep enjoy a plush ride during low load driving scenarios such as highway cruising with increased performance as each spring compresses. If you carry a significant amount of extra gear in your Jeep, some J-Rated suspension systems are available with optional high-rate coil springs to support the additional weight.
