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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I am really please with this company. Great product, i had an issue with a couple of the jonnhy joint bushings, they explained what had caused it and how to fix it. Within hrs of receiving my inquiry, i had heard back with the required info I needed. A couple hrs later problem was fixed and ready for the trail again. They care about heir product and their customers. Thanks crew, you rock

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!
