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 and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)
