Enhance Stability and Control for Any Terrain

Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Rear Track Bar, a critical suspension component designed to maintain axle centering, improve handling, and enhance stability during both on-road and off-road adventures. Whether navigating rocky trails or highway curves, this adjustable rear track bar ensures precise alignment and superior suspension performance.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.5” OD DOM tubing with a .313" wall thickness, making it significantly stronger than factory track bars for long-term durability and rugged performance.
  • Enhanced Axle Centering – Adjustable design ensures your axle remains properly centered, even after installing a lift kit or larger tires.
  • Johnny Joint for Maximum Articulation – The adjustable end features a Rock Jock Johnny Joint, delivering unparalleled flex, reduced wear, and superior off-road capability.
  • High-Grade Polyurethane Bushing – The fixed end is equipped with a durable polyurethane bushing, minimizing road vibrations and enhancing ride quality.
  • Optimized Suspension Geometry – Accommodates lifts from 0 to 6 inches, preventing axle shift, handling issues, and unnecessary drivetrain stress.

Recommended Pairing

For a fully optimized rear suspension, we recommend pairing this track bar with our Camp Series Rear Control Arm Set (CMP-J-JK-RS4) to ensure complete axle alignment and suspension stability.

Keep Your Rear Axle Centered for Maximum Control

Lifting your Jeep Wrangler JK alters suspension geometry, often causing the rear axle to shift off-center due to the factory track bar’s fixed length. This misalignment can result in uneven tire wear, poor handling, and increased drivetrain stress. The Camp Series Rear Track Bar corrects this issue with its fully adjustable design, allowing you to recenter your axle, reduce body roll, and optimize suspension performance. Whether you're rock crawling, towing, or daily driving, this track bar helps maintain a smooth, stable, and predictable ride.

Two-Stage Powder Coating for Maximum Durability

Every Camp Series Rear Track Bar undergoes a rigorous two-stage powder coating process to provide long-lasting protection against rust, corrosion, and wear.

Zinc Primer Base Coat – Forms a protective barrier against moisture, road salt, and environmental damage.

Durable Top Coat – Available in 10 color options, allowing you to customize the look of your Jeep’s suspension while adding an extra layer of durability.

Made in the USA

Manufactured in our Orem, UT facility, our Camp Series Rear Track Bar is crafted to the highest standards of American engineering. We source high-quality materials locally and oversee the entire manufacturing process, ensuring unmatched strength, precision, and performance.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

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.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

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.
