Description
Built for overlanders, racers, and serious off-road enthusiasts, the RockJock Heavy Front Antirock Sway Bar Kit for Jeep JL Wrangler, JL Unlimited, and JT Gladiator models delivers increased front suspension stability, improved load control, and enhanced performance in demanding off-road conditions. Featuring a 1-inch diameter heavy-duty torsion bar, this upgraded front sway bar is designed to support additional vehicle weight from roof top tents, overlanding gear, cargo racks, and expedition builds, while also performing in high-speed desert racing environments.
The Heavy Front Antirock Sway Bar significantly increases front roll stiffness, helping reduce body roll and improve steering control and vehicle stability on and off the road. This makes it an ideal upgrade for Jeep JL and JT builds that carry heavy loads or see aggressive off-road use.
Designed as a direct bolt-on replacement for the factory front sway bar, this system installs easily using basic hand tools. No cutting, drilling, or modifications are required, making it a straightforward suspension upgrade for 2018+ Jeep JL Wrangler, JLU Unlimited, and JT Gladiator models.
Constructed from high-strength 4340 heat-treated chromoly steel, this sway bar delivers exceptional durability and long-term reliability under extreme stress. The same material used in professional off-road competition sway bars ensures maximum strength in rugged terrain and high-performance driving situations.
When paired with a RockJock Rear Antirock Sway Bar, the system delivers a fully balanced suspension setup that improves front-to-rear handling, stability, and overall ride control. By distributing weight and traction more evenly across all four tires, the Antirock system enhances articulation, increases off-road grip, and provides a more predictable and controlled driving experience in challenging terrain.
The RockJock Heavy Front Antirock Sway Bar Kit is a proven suspension upgrade for Jeep JL Wrangler and JT Gladiator owners seeking improved load handling, better stability, and enhanced off-road performance without the need for sway bar disconnects.
Kit Fits:
- JL Wrangler Unlimited (4-door) – All Models
- JL Wrangler (2-door) – All Models
- JT Gladiator – All Models (Mojave – see notes)
Kit Includes:
- Sway Bar Torsion Bar (1 in. diameter)
- Forged 4140 Chromoly Frame Brackets (bolt-on)
- Forged Chromoly Sway Bar Arms
- UHMW Sway Bar Bushings
- Adjustable Sway Bar End Links
- All Required Hardware
Notes:
- Rubicon Models – JL and JT Rubicon models equipped with the electronic sway bar, will require the use of a tuner (Tazer or equivalent) to turn off the sway bar dash light when the factory sway bar is removed.
- JT Gladiator Mojave Models – This kit will work on Mojave models and bolt-on exactly the same, however, if the factory Mojave shocks are retained, the shock reservoirs will have to be relocated to allow the installation of the Antirock Sway Bar kit.
- Body Roll – Being that this kit features our heavy torsion bar, if this kit is used in unloaded vehicles, you may find the front 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-9900JKF and RJ-246100-101)
- 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 CE-9901D-SP4 shim pack to assist in fine tuning.
- Sway Bar Disconnects – If you are installing this Antirock Sway Bar kit in place of JKS sway bar disconnects, the sway bar disconnects would have had you cut part of the sway bar link mounting bracket off of the passenger’s side of your axle housing. In this instance, to install the Antirock, you will need to replace the thru-bolt heim joint and the hardware that comes in the Antirock kit for that location with a RJ-527000-101 studded rod end. This studded rod end will then install just like the driver’s side rod end in this kit.
