ROK Control Arms

RockJocks Johnny Joint front upper control arms for TJ Wrangler and LJ Unlimited vehicles, as well as all years of XJ Cherokee, MJ Comanche and ZJ Grand Cherokee vehicles provide length adjustability allowing pinion angle and caster angle to be adjusted. The double adjustable feature these arms allows length adjustments to the arms to be made with the arms still attached to the vehicle as well as allowing your vehicle to be upgraded to different lift amounts without having to replace the control arms in the future. Arms are made from 1 in. X.156 in. Wall DOM tubing, feature a Johnny Joint at the frame end and a fork at the housing end, are powder coated semi-gloss black, and include zerk fitted grade 8 mounting bolts. This is also a great time to replace the stock front differential housing bushings with our CE-9102K Johnny Joint front end housing conversion kit to add Johnny Joints to that point also!
