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.

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.

  • Vehicle Fitment: Jeep Wrangler JL 18+ – Eliminates rear-end wandering, improves axle alignment, and enhances handling stability for a more predictable driving experience.

  • CORE Advantage: Adjustable design allows precise axle centering, reducing body roll and preventing "dog tracking" after lifting your Jeep.

  • Adjustability: Accommodates lifts from 0 to 6 inches, ensuring proper rear axle positioning and minimizing stress on suspension components.

  • Construction: Built from 1.5" OD .313-wall DOM steel tubing with tapered polyurethane bushings for durability, vibration absorption, and improved articulation.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.
