Building off of the J-Venture systems designed for equal parts on-road handling and off-road capability, the J-Konnect system takes strength and performance a step further by adding front and rear fixed length J-Link lower control arms. These lower control arms not only add front caster and rear wheelbase, they are a serious upgrade to the strength over the factory control arms. Built 2” x .250-wall DOM tubing while offering better NVH isolation with large factory style rubber bushings at both ends. These combined with the dual rate coil springs, specially valved gas shocks, adjustable track bar, quicker disconnects and more offer improved trail performance and strength while catering to on-road handling needs.
