Overlanders and Racers! We heard you and the wait is over! Our heavy rear bar Antirock Sway Bar Kit for the rear of all JK Wrangler and Unlimited 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.

Kit Fits:

  • JK Wrangler Unlimited (4-door) – All Models
  • JK Wrangler (2-door) – All Models

Kit Includes:

  • 1 1/8 in. diameter 4130 heat treated chromoly sway bar
  • Fabricated steel frame brackets
  • Forged chromoly sway bar arms
  • Adjustable sway bar end links w/ sealed ends
  • Delrin sway bar bushings
  • Stainless braided extended brake line kit


  • Body Roll - Being that this kit features our heavy torsion bar, if this kit is used in unloaded vehicles, you may find the rear 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 for our standard 2-door kit, or our 4-door kit.
  • 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 (4 in. lift). Depending upon your specific vehicle’s lift, you may obtain shorter or longer links to suit. Additionally, all of the link rods may also be trimmed in length for fine tuning purposes.
  • Wheel & Tire Clearance - If stock JK wheels are being retained, a 1.5 in. wheel spacer is required for proper tire clearance of the Antirock sway bar end links. Aftermarket wheels should have a minimum of a 4.5 inch back spacing for proper tire clearance of the Antirock sway bar end links.

Was looking for something specific- gave them a call and was able to order it up, even though it was not on the website.

Boyfriend and I both have a set of the 2.5’ whips for our jeeps and use them every chance we get. They look for show and work even better for light in camp and on the trails. They bolt up similar to a radio antenna and have a quick release feature that we have never seen before but absolutely love. Definitely top 5 favorite accessories we’ve bought for our jeeps, and customer service is just as great as their products!
