What is included in the RockJock JT Antirock Sway Bar Kit?

This kit includes the heavy-duty 1 1/8-inch sway bar, forged 4140 chromoly arms, bolt-on steel frame brackets with Delrin bushings, adjustable heim jointed sway bar links, all necessary hardware, and installation instructions.

What is the benefit of using a heavier rear sway bar like this Antirock kit?

A heavier rear sway bar increases the rate of suspension resistance, which helps balance weight and traction across all four tires. This leads to improved traction, especially when carrying extra gear or in rugged off-road conditions.

Does this sway bar need to be disconnected for off-road use?

No, the RockJock Antirock sway bar is designed to remain connected and provide balanced suspension performance during off-road use, eliminating the need for manual disconnection.

Product Details

This RockJock Antirock sway bar kit for the rear of your 2020-2025 Jeep Gladiator includes everything you need to upgrade your suspension for serious off-road use. You get the heavy-duty 1 1/8-inch diameter, 28-spline sway bar, semi-gloss black powder-coated bolt-on steel frame brackets, Delrin frame bushings, forged 4140 chromoly arms with a semi-gloss black powder coat, adjustable length heim jointed sway bar links, all necessary hardware, and step-by-step instructions. This kit is designed to directly replace your stock rear sway bar, mounting into existing holes in the frame behind the axle and attaching to your stock axle housing.

If you're an overlander or racer, or just carry a lot of gear like roof top tents and camping equipment, this heavier bar is designed to considerably increase the rate of your rear sway bar. This helps balance and distribute weight and traction over all four tires, giving you improved traction in rugged off-road conditions. When paired with a front Antirock kit, it offers balanced performance for both front and rear suspension. The bar itself is constructed from SAE 4130 heat-treated steel, the same material used in professional off-road competition sway bars, ensuring it's built for ultimate strength.

A notable benefit of the Antirock system is that it does not need to be disconnected for off-road use, simplifying your setup and allowing you to maintain balanced suspension performance on challenging terrain. The forged arms are made from 4140 chromoly steel for added strength and durability.
