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.

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.

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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

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!
