Additional features include zerk fittings at both ends for greasing, gusseting of the Johnny Joint to the bar at the chassis end and a heavy duty flag nut at the differential end.

Product Brand Information
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-roading passion evolved into professional 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 and championships for John, and the victories have continued with various other drivers of RockJock equipped vehicles in numerous rock crawling, Ultra 4 and desert racing categories!
