2007–2018 Jeep Wrangler JK 3.6L/3.8L V6

Part #: RJ-236201-101

Overview

The RockJock Antirock Rear 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 to work in tandem with a front Antirock sway bar kit, this rear sway bar enhances suspension balance and traction across all four tires, delivering superior off-road performance. Ideal for serious off-road enthusiasts, it improves vehicle stability and weight distribution on rugged terrain without sacrificing articulation.

This kit replaces the factory rear sway bar with a robust, competition-grade component that maintains excellent on-road drivability while significantly boosting off-road capability. The RockJock Antirock sway bar is a bolt-on upgrade that does not require disconnection during off-road use, providing convenience and consistent performance in all conditions.

• Constructed from SAE 4130 heat-treated steel for exceptional strength and durability
• Fully CNC machined 7075 billet aluminum arms for precision and lightweight strength
• Semi-gloss black powder-coated steel frame brackets for corrosion resistance and long-lasting finish
• Delrin bushings for reduced friction and improved articulation
• Adjustable length heim jointed sway bar links for fine-tuning suspension response
• Long travel stainless braided brake lines that relocate brake lines inboard for sway bar arm clearance

Construction & Design

The RockJock Antirock sway bar is crafted from premium SAE 4130 heat-treated steel, the same material trusted in professional off-road racing applications. This ensures maximum strength and resistance to bending or fatigue under extreme conditions. The kit’s arms are precision CNC machined from 7075 billet aluminum, combining lightweight design with exceptional rigidity. The semi-gloss black powder-coated steel brackets provide robust mounting points while resisting corrosion and wear.

Delrin bushings are used to reduce friction and wear, allowing smooth articulation and improved suspension movement. The adjustable heim jointed links enable precise tuning of sway bar stiffness to match driver preference and terrain demands. Stainless braided brake lines are included to safely relocate brake lines away from sway bar arms, preventing interference during suspension travel.

Installation & Fitment

This sway bar kit is designed for direct bolt-on installation using existing mounting points on the Jeep Wrangler JK 2-door models from 2007 to 2018 with 3.6L or 3.8L V6 engines. No frame drilling or welding is required, simplifying the upgrade process. The kit includes all necessary hardware and detailed instructions to guide you through the installation.

Because the RockJock Antirock sway bar does not require disconnection for off-road use, it offers continuous performance without the hassle of manual adjustments. However, users should be aware that this sway bar will increase body roll compared to the stock setup and may alter on-road handling characteristics.
