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.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

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!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.
