RockJock's Antirock rear sway bar kit for all JK Wrangler Unlimiteds, 4-door), 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 billet aluminum arms, semi-gloss black powder coated bolt-on steel frame brackets, delrin bushings, adjustable length heim jointed sway bar links, long travel stainless braided brake lines that relocate the brake line inboard of the frame for sway bar arm clearance, necessary hardware, and step-by-step instructions. Unit bolts into existing holes in the bottom of the frame rail 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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

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!
