About RockJock

RockJock develops Antirock systems around heat-treated torsion bars, application-specific frame mounting, and serviceable link geometry. The JL rear kits are offered in multiple bar rates and arm materials so the bar can match vehicle load and intended use.

Related Parts

• No internal front bar, alternate link, or shim is linked because those parts must match the exact JL engine, load, lift height, frame width, and desired roll balance.

FAQ

It is a rear one-inch Antirock sway-bar kit with billet arms for supported Jeep Wrangler JL two- and four-door models.

Yes. RockJock lists the kit for Wrangler JL and Wrangler Unlimited JL models.

No. The Antirock system is designed to remain connected during off-road use.

The one-inch bar is made from 4340 heat-treated chromoly.

The exact kit uses fully CNC-machined 7075 aluminum arms.

No. They target RockJock's 3.5-inch suspension and may require an approved shorter, longer, or trimmed link arrangement for another ride height.

Yes. Sway-bar rate and vehicle loading affect roll behavior, so use controlled road testing and match the front and rear setup to the build.

No. Heavily loaded builds may require RockJock's separate 1 1/8-inch rear kit rather than this one-inch configuration.

Installation Instructions

1. Confirm the JL rear application, vehicle load, ride height, and link requirements before unpacking RJ-246202-101.
2. Support the Jeep safely, remove the factory rear sway bar, and inspect the frame and axle mounting points.
3. Install the billet frame brackets and UHMW bushings in the documented orientation, using shims only where RockJock specifies.
4. Center the torsion bar, install the billet arms at equal indexing, and set the adjustable links without preload at ride height.
5. Cycle the suspension and inspect tire, brake-line, exhaust, driveline, frame, arm, and link clearance through full travel.
6. Torque all hardware, complete a controlled road test, and recheck fasteners, arm position, and link clearance after initial use.
