Product Details

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.

Optional Hardware Upgrade

Designed for easy installation using factory hardware, but if your Jeep has rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a smooth installation.


  • Vehicle Fitment: Jeep Wrangler JK 07-18 – Precision-engineered for all trims to maintain axle alignment and improve handling on any terrain.

  • CORE Advantage: Eliminates axle shift, enhances stability, and improves suspension geometry for better control and reduced drivetrain stress.

  • Adjustability: Fully adjustable to accommodate 0–6” lifts, ensuring precise rear axle centering and alignment after suspension modifications.

  • Construction: Built from 1.5” OD .313-wall DOM tubing with a Johnny Joint at the adjustable end and a polyurethane bushing at the fixed end for durability and vibration dampening.

  • 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.

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!

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.
