RockJock heavy Antirock rear sway bar kit fits all Jeep JK Wrangler models and features a 1-1/8" diameter, 28-spline bar made from 4130 heat-treated chromoly. The heavier bar raises the rear roll rate for loaded overlanding rigs or desert use, bolts on with hand tools and replaces the stock rear sway bar.
