ROK Control Arms

RockJocks complete set of all Johnny Joint adjustable length control arms for JK Wrangler and JK Wrangler Unlimited vehicles provides length adjustability on all arms, allowing the pinion angle and caster angle to be adjusted. 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. To allow complete unrestricted movement, RockJocks Johnny Joint rod ends used at both ends of all 4 of the rear arms, both ends of the front lowers, and on one end of the front upper arms. Upper arms are made from 1.25 in. O. D. X.188 in. Wall DOM steel tubing and feature 1 in.-14 adjustable axle housing forks at the axle end and 1 in.-14 adjustable Johnny Joints on the rear uppers. Lower arms are 1.625 in. O. D. X.250 in. Wall DOM and feature 1 1/4 in.-12 thread adjustable Johnny Joints. All arms are powder coated semi-gloss black, and are fitted zerk fittings for greasing. This is also a great time to replace the stock front differential housing bushings with our CE-9102JK Johnny Joint front end housing conversion kit to add Johnny Joints to that point also!
