RockJock's Antirock Sway Bar Kitfor the rear of all JL Wrangler and Unlimited vehicles helps free up suspension articulation to increase off-road traction. The Antirock sway bar easily bolts on with hand tools and is designed to directly replace the vehicle's stock rear sway bar. The Antirock does not require disconnecting for off-road use!The sway bar is made of 4130 heat treated chromoly for ultimate strength, which is the same quality used in professional off-road competition sway bars.Kit Fits:JL Wrangler Unlimited (4-door) - All ModelsJL Wrangler (2-door) - All ModelsKit Includes:Sway Bar Torsion Bar (1 in. diameter)Billet UHMW Frame BushingsForged Chromoly Sway Bar ArmsAdjustable Sway Bar End LinksAll Required HardwareNotes:Body Roll - This 1 in. bar Antirock sway bar kit, in most cases will provide an unloaded JL similar sway control to that of a factory sway bar.Overlanding - If you are an overlander and will be loading your vehicle down with weight above door handle level (bed racks, roof tents, etc.), ourRJ-246200-101kit with the heavy, 1 1/8 in. diameter bar will most likely be more appropriate for your application.End Links - Out of the box, the length of the sway bar's vertical links that are included in this kit are intended for use with our suspension systems (3.5 in. lift). Depending upon your specific vehicle's lift, you may obtain shorter or longer links to suit. Additionally, all of the link rods may also be trimmed in length for fine tuning purposes.Fitment - It is quite common for factory frames to vary in width. If you find your vehicle's frame to be on the narrower side, the Antirock arms can simply be slid on until they are snug against the Antirock bushings and then the arms clamped down. However, on some frames the arms absolutely have to hold true width to clear bolt heads on the side of the frame, etc.
