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.

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!

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)

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.
