Description
Built for overlanders, racers, and serious off-road enthusiasts, the RockJock Heavy Rear Antirock Sway Bar Kit for Jeep JL Wrangler and Wrangler Unlimited models delivers increased rear suspension stability, improved load control, and enhanced performance in demanding conditions. Featuring a 1-1/8-inch diameter, 28-spline heavy-duty torsion bar, this upgraded rear sway bar is designed to handle the added weight of overlanding gear such as roof top tents, cargo racks, camping equipment, and expedition builds, while also performing in high-speed desert racing applications.
The heavy-duty Antirock Rear Sway Bar significantly increases rear roll stiffness, helping improve vehicle stability, reduce body roll, and maintain better control on and off the road. This makes it an ideal suspension upgrade for Jeep JL owners running heavily loaded or performance-oriented builds.
Designed as a direct bolt-on replacement for the factory rear sway bar, this system installs easily using basic hand tools. No cutting, drilling, or modifications are required, making it a straightforward upgrade for 2018+ Jeep JL Wrangler and JLU Unlimited models.
Constructed from high-strength 4340 heat-treated chromoly steel, the sway bar delivers exceptional durability and long-lasting performance under extreme off-road and high-load conditions. This is the same premium material used in professional off-road competition sway bars, ensuring maximum strength and reliability in harsh environments.
The RockJock Heavy Rear Antirock Sway Bar Kit is a proven suspension upgrade for Jeep JL Wrangler owners seeking improved load handling, better stability, and enhanced off-road performance without the need for sway bar disconnects.

Notes:
- Body Roll – Being that this kit features our heavy torsion bar, if this kit is used in unloaded vehicles, you may find the rear sway bar to be stiffer than you would prefer. This kit is intended for use on vehicles that are loaded down with a rack, roof top tent, camping gear, etc. If this does not sound like your application, you may be more of a customer of our lighter rate bar kits (CE-9900JLR4 and CE-9900JLR4A)
- 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, 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 RJ-207001-1SP4 shim pack to assist in fine tuning.
