JKS Manufacturing adds to its control arm offerings with new J-Flex lower control arms for the front of the 1999-2004 Jeep Grand Cherokee WJ. These new J-Flex arms offer improved strength and performance along with adjustability to correct front caster on lifted applications. The arms are built from 2” OD x .250-wall DOM tubing, formed for additional clearance. At the axle mount these arms feature premium Clevite® rubber bushings to absorb noise and reduce vibrations for a comfortable, quiet ride and maitenance-free operation. At the other end the arms incorporate a unique hex-shaped threaded bung for to allow easy adjustment of the forged flex end and jam nut. This forged end uses 1-1/4”-12 threads to provide the ultimate strength and fine adjustments. The flex end design allows for 30-degrees of misalignment (15 in either direction) for impressive articulation. They are greaseable to ensure long bushing life and easily rebuildable if and when the time comes. As with all JKS control arms, these J-Flex lower control arms come finished in a durable gloss black powder coat finish and are backed by JKS’s limited lifetime warranty. Upgrade your Grand Cherokee WJ’s front lower control arms with the new J-Flex arms from JKS Manufacturing.
