RockJock's Antirock rear sway bar kit for JL Wranglers and Unlimiteds, when used in conjunction with a front Antirock sway bar kit, provides balanced performance of front and rear suspension for rugged off-road conditions. It gives the driver increased traction by balancing and distributing the weight and traction over all four tires. The Antirock off road sway bar is designed to directly replace the stock Jeep sway bar. This bar is made of SAE 4130 heat treated steel for ultimate strength, which is the same quality used in professional off-road competition sway bars. This kit includes all components for installation including, the sway bar, beautiful, fully CNC machined 7075 billet aluminum arms, semi-gloss black powder coated bolt-on steel frame brackets, delrin frame bushings, adjustable length heim jointed sway bar links, necessary hardware, and step-by-step instructions. Unit mounts into frame crossmember in front of the axle and attaches to the stock mounts on the vehicle's axle housing. The RockJock Antirock sway bar does not need to be disconnected for off-road use. CAUTION: Jeeps will have more body roll than stock. This sway bar may be used on the street, however, it will not provide the same handling characteristics as the stock setup.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.
