Overlanders and Racers! RockJock heard you and the wait is over! Their heavy bar Antirock Sway Bar Kit for the rear of all Jeep JK Wrangler models features a 1 1/8 in. diameter, 28 spline bar! This heavier bar considerably increases the rate of the rear sway bar for those with racks, roof top tents, camping gear, etc. This heavy bar kit is also applicable to desert racing applications. This kit easily bolts on with hand tools and is designed to directly replace the vehicle’s stock rear sway bar. The sway bar is made of 4130 heat treated chromoly for ultimate strength, which is the same quality used in professional off-road competition sway bars. The Antirock rear sway bar, when used in conjunction with a front Antirock sway bar, provides a more stable feeling cabin and balanced performance of front and rear suspension in rugged off-road conditions. Antirocks gives the driver increased traction by balancing and distributing the weight and traction over all four tires.

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.

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.
