Correct geometry and increase the strength of your Jeep Wrangler JL by with heavy duty JKS J-LINK rear lower fixed length control arms. J-Link arms offer improved strength and performance while correcting front caster on lifted applications. The arms are built right here in the USA from 2" OD x .250-wall DOM tubing. The front arms are 5/16" longer that stock to correct front caster. They install in the OE mounting locations for 0-4.5" of lift. In the rear, the lower control arms are 1/4" longer than stock to help recenter the axle in the wheel well when used with lift kits. Both ends of these arms feature pre-installed premium OE style rubber bushings to absorb noise and reduce vibrations for a comfortable, quiet ride. When used in combination with JKS Jspec systems these arms can be used in place of the lower cam lock modification. They come finished in a durable gloss black powder coat finish and are backed by JKS's limited lifetime warranty.
