RockJock Antirock Sway Bar Kit
2007–2018 Jeep Wrangler JK 3.6L/3.8L V6 4 Door
Part #: RJ-236202-101
Overview
The RockJock Antirock Rear Sway Bar Kit is engineered specifically for Jeep Wrangler JK Unlimited 4-door 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, this kit enhances suspension balance and traction across all four tires during demanding off-road conditions. By distributing weight more evenly, it improves vehicle stability and traction, giving drivers greater confidence on rugged terrain without sacrificing everyday usability.
This rear sway bar is a direct replacement for the factory unit, providing a robust upgrade that maintains the Jeep’s off-road capability without requiring disconnection during trail use. While it increases body roll compared to stock sway bars, it delivers superior off-road articulation and traction, making it ideal for serious off-road enthusiasts who want improved performance without compromising reliability.
Key Features
The RockJock Antirock Rear Sway Bar Kit combines advanced materials and thoughtful engineering to deliver durable, high-performance suspension enhancement:
- Constructed from SAE 4130 heat-treated steel for exceptional strength and durability
- Fully CNC-machined 7075 billet aluminum arms for precision and lightweight performance
- Semi-gloss black powder-coated steel frame brackets for corrosion resistance and long-lasting finish
- Delrin bushings to reduce friction and wear, ensuring smooth operation
- Adjustable length heim jointed sway bar links for customizable suspension tuning
- Long-travel stainless braided brake lines that relocate brake lines inboard for clearance
- Bolts directly into existing frame holes and attaches to stock axle mounts for straightforward installation
- Designed to remain connected during off-road use, eliminating the need for manual disconnection
Construction & Design
The RockJock Antirock sway bar is built with competition-grade SAE 4130 heat-treated steel, a material renowned for its toughness and fatigue resistance in extreme off-road environments. The billet aluminum arms are crafted from 7075 aluminum, a premium alloy known for its high strength-to-weight ratio, precision-machined to exact tolerances for optimal fit and function.
Steel frame brackets are powder coated in a semi-gloss black finish to resist corrosion and wear, while Delrin bushings provide durable, low-friction pivot points that enhance articulation and longevity. The adjustable heim joint links allow fine-tuning of sway bar geometry to suit different driving styles and terrain.
Installation & Fitment
This kit is designed for a direct bolt-on installation using existing mounting points on the Jeep Wrangler JK frame and axle housing. It includes all necessary hardware and detailed step-by-step instructions, making it accessible for experienced DIYers and professional installers alike. No welding or frame modifications are required.
The brake lines are upgraded and relocated inboard of the frame to prevent interference with the sway bar arms during suspension travel, ensuring safe and reliable operation. The sway bar remains connected during off-road use, providing continuous traction benefits without the inconvenience of manual disconnection.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
