For serious off-road use, step up to a JKS J-Konnect 2.5" suspension system for your Diesel 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, custom-valved FOX 2.0 Performance Series monotube gas 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.
