Enhance Your Stability and Control

Stability and control are paramount for off-road adventures, and the Crawl Series Rear Track Bar (CRL-J-JK-RTB1) is engineered to deliver both. Designed specifically for Jeep Wrangler JK models (2007-2018), this track bar ensures axle center alignment is maintained, providing superior handling and stability even over rough terrain or during aggressive cornering.

Key Features and Benefits

  • Exceptional Stability and Handling – Effectively minimizes body roll during cornering and maintains precise axle alignment, improving vehicle control in challenging off-road conditions.
  • Premium Construction for Durability – Constructed from 1.5” OD .313 Wall DOM Tubing and featuring a welded Johnny Joint at the fixed end and a forged Johnny Joint at the adjustable end, this track bar is designed to withstand extreme stress and perform reliably under demanding conditions.
  • Adjustability for Lifted Vehicles – Fully adjustable to accommodate lifts from 0 to 6 inches, allowing for precise axle re-centering and suspension geometry optimization. Custom solutions are available for lifts over 6 inches upon request.
  • Improved Suspension Harmony – Designed to integrate seamlessly with other Crawl Series components, this track bar works in unison with your suspension system to deliver consistent and predictable performance both on and off the trail.

Two-Stage Powder Coating

To ensure long-lasting durability and resistance to corrosion, every Crawl Series Rear Track Bar undergoes a two-stage powder coating process. A zinc primer base coat provides a strong barrier against rust, while the durable top coat offers an extra layer of protection. Available in 10 customizable colors, the finish not only enhances durability but also allows you to personalize your suspension components to match your Jeep’s aesthetic.

Made in the USA

Proudly designed and manufactured in Orem, UT, the Crawl Series Rear Track Bar represents the pinnacle of American craftsmanship. With meticulous attention to quality and performance, this product supports local industries while delivering exceptional reliability for your Jeep.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

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!

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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

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!
