Overview

The RockJock Antirock Rear Bolt-On Sway Bar Kit is engineered specifically for Jeep Wrangler JK models from 2007 through 2018 equipped with 3.6L or 3.8L V6 engines. Designed for off-road enthusiasts seeking enhanced traction and suspension balance, this rear sway bar works in harmony with a front Antirock sway bar kit to optimize weight distribution and tire contact across all four wheels. By improving suspension articulation and stability, it delivers superior control and confidence on rugged terrain without the need to disconnect the sway bar during off-road use.

• Adjustable length heim jointed sway bar links for precise tuning and improved suspension articulation
• Delrin bushings for reduced friction and long-lasting performance
• Semi-gloss black powder-coated steel frame brackets for corrosion resistance and rugged aesthetics

• Complete hardware kit and detailed step-by-step installation instructions included
• Designed to maintain sway bar engagement on and off-road, eliminating the need for manual disconnection

Construction & Design

The RockJock Antirock rear sway bar is crafted from premium SAE 4130 heat-treated steel, renowned for its high strength-to-weight ratio and toughness in extreme environments. The forged 4140 chromoly arms further enhance durability, ensuring the sway bar withstands the rigors of aggressive off-road driving. The semi-gloss black powder coating protects against corrosion and wear, extending the lifespan of the components.

Delrin bushings are employed to minimize friction and provide smooth articulation, while the adjustable heim joints allow for fine-tuning suspension geometry. The stainless braided brake lines are engineered for flexibility and durability, repositioning the brake lines safely away from potential interference with the sway bar arms.

Installation & Fitment

This kit is designed for a straightforward bolt-on installation using existing mounting points on the Jeep Wrangler JK frame and axle housing. No welding or frame modifications are required, making it accessible for experienced DIYers and professional installers alike. The included hardware and comprehensive instructions guide users through each step, ensuring a secure and precise fit.

Compatible with 2007–2011 Jeep Wrangler JK models with the 3.8L V6 engine, 2012–2017 JK models with the 3.6L V6, and the 2018 JK 3.6L V6, this sway bar kit integrates seamlessly with the vehicle’s suspension system. Note that while the sway bar enhances off-road traction and articulation, it may increase body roll compared to the stock setup and will alter street handling characteristics.
