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.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

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.

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.
