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, semi-gloss black powder coated bolt-on steel frame brackets, delron frame bushings, forged 4140 chomoly arms, 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.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
