Product details
For serious off-road use, step up to a JKS J-Konnect 2.5" suspension system for your JL Wrangler. 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, your selection of Jspec of Fox shocks, an adjustable track bar, Quicker Disconnect sway bar end links, and more. J-Konnect™ is ready for aggressive trail performance. Now available with the new Fox 2.5 Performance Series shocks! The 2.5" aluminum bodies with a race-developed main piston and true internal floating piston (IFP) separate gas and oil to provide consistent and fade-resistant performance. The 2.5-inch piston offers a greater force capability by moving more fluid and increasing damping and is less prone to cavitation. J-Konnect: Builds on J-Venture with heavy-duty J-Link lower control arms to improve strength and correct geometry. J-Konnect 2.5" Lift Kit
