Cruise Series Rear Track Bar – Compatible with Jeep Wrangler JL (CRS-J-JL-RTB1)

Eliminate Rear-End Wandering and Dog Tracking

If you've noticed your Jeep Wrangler JL feeling unstable, wandering on the highway, or "dog tracking" (where the rear end shifts sideways instead of staying aligned with the front), our Cruise Series Rear Track Bar is the solution. Designed to keep your rear axle properly centered, this adjustable rear track bar corrects alignment after lifting your vehicle, improving handling, reducing body roll, and eliminating rear-end instability.

What’s Included in the Kit?

  • Cruise Series Rear Track Bar (CRS-J-JL-RTB1)

Key Features and Benefits

  • Eliminates Rear Wandering and Dog Tracking – Re-centers your rear axle to keep your Jeep driving straight, preventing the unstable, unpredictable handling caused by factory geometry.
  • Heavy-Duty DOM Tubing Construction – Built from 1.5" OD .313 Wall DOM steel tubing, ensuring maximum strength and long-lasting durability.
  • Precision Adjustability for Lifted Vehicles – Accommodates lifts from 0 to 6 inches, ensuring proper axle alignment and eliminating the common issue of axle shift after a suspension lift.
  • Tapered Polyurethane Bushings – Provides smoother articulation, absorbs vibrations, and enhances ride comfort compared to factory rubber bushings.
  • Reduces Stress on Suspension Components – A properly centered axle prevents premature wear on suspension and drivetrain components, extending the life of your Jeep’s critical systems.
  • Recommended Pairing for a Complete Suspension Solution – For full rear-end alignment and enhanced handling, pair with our Cruise Series Rear Control Arm Set (CRS-J-JL-RS4).

Two-Stage Powder Coating for Maximum Protection

Every track bar undergoes a two-stage powder coating process to resist rust, corrosion, and road debris damage: Zinc Primer Base Coat – Creates a strong barrier against rust and corrosion, ensuring longevity in harsh conditions. Customizable Top Coat – Available in 10 different colors, allowing you to match your Jeep’s aesthetic while adding another layer of protection.

Made in the USA

We proudly manufacture our Cruise Series Rear Track Bar in Orem, UT, maintaining complete control over the production process to ensure top-tier quality and durability.

Optional Hardware Upgrade

This track bar installs using factory hardware, but if you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits to simplify installation and ensure a secure fit.

In Conclusion

Upgrading to our Cruise Series Rear Track Bar eliminates rear-end wandering, dog tracking, and instability, ensuring precise alignment and a confidence-inspiring ride. Whether you're tackling trails or driving on the highway, this track bar provides improved stability, reduced suspension stress, and long-term durability.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
