RockJocks Johnny Joint front upper control arms for JK Wrangler and JK Wrangler Unlimited vehicles provide length adjustability allowing pinion angle to be adjusted after the installation of a suspension lift. Additionally the adjustable feature of our arms allows your vehicle to be upgraded to different lift amounts without having to replace the control arms in the future. Arms are fabricated from 1.25 in. o.d. x .188 in. wall DOM steel tubing and feature a 2 in. Johnny Joint rod end on one end, and a formed steel fork and jam nut on the other end. Arms are finished in semi-gloss black powder coat. Add the CE-9102JK Johnny Joint kit to your front differential to attain maximum articulation from your upper control arms!
