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 of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

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

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4
