Description
Built for overlanders, racers, and serious off-road enthusiasts, the RockJock Heavy Rear Antirock Sway Bar Kit for Jeep JT Gladiator delivers increased rear suspension control, improved stability, and enhanced articulation for demanding off-road and high-load applications. Featuring a massive 1-1/8-inch diameter, 28-spline torsion bar, this heavy-duty rear sway bar is designed to handle the added weight of overlanding setups including roof top tents, bed racks, camping gear, and expedition accessories, while also performing in high-speed desert racing conditions.
Installing the Antirock Rear Sway Bar helps free up suspension articulation, increasing off-road traction, improving four-wheel contact, and enhancing overall vehicle stability on uneven terrain. In addition, the system helps keep the vehicle more level in off-camber situations, reducing body roll and improving driver confidence in technical off-road environments.
The RockJock Antirock system is a direct bolt-on replacement for the factory rear sway bar and installs easily using basic hand tools. No cutting, drilling, or sway bar disconnects are required, making it a simple and reliable suspension upgrade for Jeep JT Gladiator models.
Constructed from high-strength 4130 heat-treated chromoly steel, the sway bar delivers exceptional durability and long-term performance under extreme off-road stress. This is the same material specification used in professional off-road competition sway bars, ensuring maximum strength and reliability in harsh conditions.
For maximum performance builds, this kit also includes forged 4340 sway bar arms featuring a vertical offset design that increases suspension up-travel while maintaining exceptional rigidity through an I-beam cross-section structure. The arms include two adjustable sway bar link mounting positions, allowing the included RJ-201000-101 Double Sheer End Link Bracket Kit to be configured for optimal clearance and fitment.
These adjustable brackets add 1.5 inches of effective arm length and allow for up to 1.25 inches of side-to-side end link adjustment, enabling precise tuning for different lift heights, tire sizes, and suspension setups. This ensures maximum clearance, improved articulation, and a fully optimized rear sway bar configuration for your Jeep JT Gladiator build.

Notes:
- Body Roll – Being that this is our heavy, overlanding/racing rate bar, if this kit is used on an unloaded vehicle on the street, expect it to be stout!
- 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 links to suit less lift, here. If you require longer links than this kit includes, for more lift, you may either modify the links in the kit or new links may have to be fabricated.
- Fitment – This bolt-on kit is designed to bolt to the vehicle’s factory frame and any factory JT rear axle option. If your vehicle build features an aftermarket rear axle, you will have to address the end link mounting point at the axle by modifying the brackets in the kit or fabricating new mounting tabs to suite. See our universal link mounting tab offerings here.
Additionally, 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 RJ-207001-1SP4 shim pack to assist in fine tuning.
