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 amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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.
