CE-9900TJR – TJ/LJ Antirock Rear Sway Bar Kit

Improve suspension performance and off-road capability with the RockJock Antirock Rear Sway Bar Kit for Jeep TJ Wrangler and LJ Wrangler Unlimited models. Designed to increase suspension articulation and maximize traction, the Antirock sway bar allows your Jeep to maintain better four-wheel contact on uneven terrain, providing improved stability and confidence on the trail. At the same time, the system helps reduce excessive body roll and minimizes the unsettling tipping sensation often experienced during off-camber obstacles. Unlike factory sway bars that can limit suspension travel, the RockJock Antirock Rear Sway Bar is engineered to deliver balanced handling both on and off the road. The system is designed to replace the factory rear sway bar and eliminates the need for disconnects, allowing you to transition from highway driving to off-road adventures without stopping to make adjustments. Installation is straightforward and can be completed with basic hand tools, making it an easy bolt-on upgrade for Jeep TJ Wrangler and Wrangler Unlimited (LJ) owners seeking increased off-road performance without sacrificing on-road comfort. At the heart of the system is a high-strength 4340 heat-treated chromoly sway bar, manufactured to the same standards used in professional off-road competition vehicles. This premium material delivers exceptional durability and performance, making the RockJock Antirock Rear Sway Bar Kit one of the most trusted suspension upgrades available for 1997-2006 Jeep TJ Wrangler and 2004-2006 Jeep Wrangler Unlimited (LJ) models. Whether you’re building a dedicated rock crawler, trail rig, or dual-purpose Jeep, the RockJock Antirock Rear Sway Bar Kit provides increased articulation, improved traction, and reliable performance without the hassle of manual sway bar disconnects. Kit Fits: TJ Wrangler TJ Wrangler Unlimited (LJ) Kit Includes: Sway Bar Torsion Bar (.800 in. diameter) Fabricated Steel Frame Brackets Forged Chromoly Sway Bar Arms UHMW Sway Bar Bushings Adjustable Sway Bar End Links Weld-On End Link Axle Tabs All Required Hardware Notes: Body Lift – Ideally, this kit installs easiest on vehicles with a 1 in. body lift. It can be used without a body lift, but some minor pinch weld trimming underneath the back of the body tub is mandatory. Additionally, due to the age of TJ and LJ vehicles, we see a lot of the rubber body pucks have deteriorated with time, making the non-body lift installation that much more difficult – but it is possible. Body Roll – Antirock sway bar equipped vehicles will exhibit more body roll than vehicles equipped with the stock sway bar. Antirock sway bars may be used on the street, however, they do not provide the same handling characteristics as the stock sway bar. Body Trimming – The plastic inner fender liners and, on most models, some of the inner wheelwell sheet metal must be trimmed for Antirock sway bar arm up travel. See the instruction manual for more details. 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 (4 in. lift). Depending upon your specific vehicle’s lift, you may obtain shorter or longer links to suit, here. 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. In instances of this nature, see our CE-9901D-SP4 shim pack to assist in fine tuning. Welding – Installation of this kit requires you to weld the supplied tabs to the rear axle housing, to provide a mounting point for the bottoms of the sway bar links. Shock Travel – This kit is intended for use with 12 in. travel shocks. Wheel and Tire Clearance – This kit was designed around a 15 in. x 8 1/2 in wheel with a 4 1/2 in. back space and 35 in. x 12.50 in. tires. If what you are installing deviates from these specs., or if stock TJ/LJ wheels are being retained, you will have adjust as necessary, up to and including the use of wheel spacers. In some tight fitment applications, it may be necessary to purchase these thin nyloc nuts, to be used on the heim joint studs at the end of the arm, allowing you to trim excess heim joint thread off to gain more tire clearance.
