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.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

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!

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 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.

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!

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!
