Superior Vehicle Stability

Maximize your Jeep Wrangler TJ or LJ’s stability and control with the Crawl Series Rear Track Bar. Designed to keep your axle centered, this essential component ensures precise handling whether you're tackling rugged trails or navigating daily commutes. Its heavy-duty construction and extreme adjustability make it a crucial upgrade for anyone looking to improve their Jeep’s performance, particularly for lifted vehicles.

Key Features and Benefits

  • Exceptional Flexibility Off-Road Performance – Equipped with Rock Jock Johnny Joints at both ends, this track bar delivers unmatched articulation, control, and stability on rough terrains. It allows your suspension to flex freely, reducing binding and improving overall ride quality.
  • Heavy-Duty Construction – Built from 1.5" OD 5/16” Wall DOM tubing, this track bar is engineered for superior strength and longevity. The Johnny Joints provide exceptional durability and smooth operation, ensuring this track bar withstands extreme off-road conditions.
  • Complete Rear-End Suspension Enhancement – Pairing this rear track bar with our Crawl Series Rear Control Arms Set creates a fully adjustable rear suspension system, ensuring axle alignment, optimal handling, and superior off-road capability.

Perfect Fit for Lifted Jeeps

When lifting your TJ or LJ, the axle shifts laterally, impacting alignment and suspension geometry. Our adjustable rear track bar corrects this issue, re-centering the axle for better drivability, reduced tire wear, and improved suspension function.

  • For 0 to 3-inch lifts, this track bar is a direct bolt-in upgrade.
  • For 3+ inch lifts, or vehicles with an SYE, a corrected rear axle mount is required due to the steeper pinion angle rotation and clearance issues between the bar and the factory mount.

Two-Stage Powder Coating for Maximum Durability

For maximum durability and corrosion resistance, every Crawl Series Rear Track Bar undergoes a two-stage powder coating process.

Zinc Primer Base Coat – Provides a strong barrier against rust.

Durable Top Coat – Available in 10 color options for lasting protection and a personalized aesthetic.

Made in the USA

Designed and manufactured at our Orem, UT facility, the Crawl Series Rear Track Bar reflects top-tier American craftsmanship. By overseeing every aspect of production and sourcing high-quality local materials, we guarantee uncompromising durability and performance.


  • Vehicle Fitment: Jeep Wrangler TJ LJ 97-06 – Improves rear axle stability, enhances handling, and reduces suspension stress for a smoother ride. Prevents rear axle shift in lifted applications, ensuring precise alignment.

  • CORE Advantage: Recenters the rear axle left to right under the Jeep, helping correct dog tracking and misalignment caused by lift modifications. Enhances rear-end stability and improves handling over uneven terrain.

  • Adjustability: Fully adjustable for 0 to 6-inch lifts, allowing precise axle centering and alignment correction. For lifts above 6 inches or SYE-equipped Jeeps, additional tuning may be necessary for optimal suspension performance.

  • Construction: Built from 1.5" OD 5/16” wall DOM tubing for superior strength. Features Johnny Joints at both ends to maximize articulation, eliminate binding, and improve suspension movement over rugged off-road terrain.

  • 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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

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!

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

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.
