Replace the front differential housing upper control arm bushings on your 1997-2006 Jeep TJ Wrangler, LJ Unlimited or all years of XJ Cherokee or MJ Comanche vehicles with Johnny Joint(R) rod ends from RockJock to get maximum articulation out of your suspension! This kit includes a Johnny Joint(R) insert for gear case ear and installation tool, as well as 1 in. thick flame-cut steel upright for the tube side, with the Johnny Joint(R) already installed. This kit has you cut off the top of the stock bracket that is on the tube and install the new RockJock piece into the existing bracket base. You then weld the RockJock piece to the existing bracket base. This allows for no welding to be done on the tube, resulting in no warpage of the tube.This kit requires cutting and welding equipment for installation!!! NOTE: This kit included larger than stock, 1/2 in. greasable hardware for use in performance applications! Control arm holes will have to be drilled to accept the 1/2 in. bolts.

RockJock by John Currie's roots run deep as jeeping has been a love of the Currie family for decades. In his off-roading adventures, John pushed the limits of his vehicles coming to the realization of the shortcomings of the equipment. Thus it became John's goal to design and build the best-performing, strongest, most durable products on the market. A Jeep suspension upgrade product line was first developed in the 1980s based around Jeep CJ and YJ vehicles. Fast forward to 1998 and John's off-road passion evolved into rock crawling competitions. In 2001, John Currie took home the 1st place trophy in the Extreme Rock Crawling Championship Series, in a RockJock equipped Jeep TJ Wrangler. This was the first of many victories for John and various RockJock equipped vehicles in numerous rock crawling, Ultra 4 and desert racing championships! RockJock continues to progress and innovate as new platforms of vehicles are introduced. From the JK Wrangler, the JL Wrangler and JT Gladiator, John Currie personally continues to design, build, test, sell, and install the finest, cutting-edge, high-end suspension, steering and towing components available.
