Experience Unsurpassed Stability

For Jeep Wrangler JK owners (2007-2018), the Crawl Series Front Track Bar is the ultimate solution for maintaining axle alignment and ensuring stability during off-road adventures. Whether tackling rough terrain or navigating sharp corners, this track bar delivers outstanding control and handling, making it an essential component of your solid axle suspension system.

Key Features and Benefits

  • Durable, Premium Quality Construction – Engineered for strength and longevity, the Crawl Series Front Track Bar is crafted from 1.5" OD .313 Wall DOM Tubing, far surpassing industry standards. Equipped with Rock Jock Johnny Joints at both ends, it delivers unparalleled articulation and durability, standing up to even the toughest off-road conditions.
  • Adjustability for a Perfect Fit – Lifting your vehicle can often lead to axle shift due to changes in suspension geometry. The Crawl Series Front Track Bar is fully adjustable, enabling precise axle re-centering and reducing stress on your suspension components. This track bar accommodates lifts from 0 to 6 inches, ensuring optimal alignment and handling. For vehicles with lifts beyond 6 inches, additional solutions are available upon request.
  • Two-Stage Powder Coating for Longevity – Every Crawl Series Front Track Bar undergoes a rigorous two-stage powder coating process, starting with a zinc primer base coat for superior corrosion resistance. A durable top coat, available in 10 color options, adds an extra layer of protection and customization to match your Jeep's style.

Made in the USA

Proudly manufactured in Orem, UT, the Crawl Series Front Track Bar is a testament to American craftsmanship. By maintaining full control over the manufacturing process, we ensure exceptional quality and competitive pricing.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

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!
