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.

What's Included?

  • Camp Series Rear Track Bar (CMP-J-JK-RTB1)

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.

In Conclusion

The Camp Series Rear Track Bar is an essential upgrade for Jeep Wrangler JK owners looking to maintain proper axle alignment, improve handling, and enhance overall drivability. With heavy-duty construction, full adjustability, and premium joints, this track bar ensures a smoother ride, better suspension articulation, and maximum durability. Upgrade today and experience the CORE 4X4 difference in quality, performance, and American craftsmanship!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

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.

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.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

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.
