Product Details

Achieve Superior Stability and Control

Upgrade your Jeep Wrangler JL’s suspension with the Camp Series Rear Track Bar, designed for model years 2018-Present. This adjustable track bar is a crucial suspension upgrade, ensuring that your axle remains centered after lifting your Jeep. Whether you're on highway drives or off-road trails, this track bar minimizes body roll, improves handling, and enhances suspension geometry for a smoother, more controlled ride.

Key Features and Benefits

  • Heavy-Duty Construction – Built from 1.5" OD .313 Wall DOM tubing, providing superior strength and durability compared to factory components.
  • Optimized Suspension Geometry – Fully adjustable design allows you to recenter the rear axle and improve suspension performance, accommodating lifts from 0 to 6 inches.
  • Premium Joint Technology – Features a Johnny Joint at the adjustable end for articulation and a high-grade polyurethane bushing at the fixed end to absorb road vibrations.
  • Recommended Pairing – For a fully optimized rear suspension system, pair this track bar with our Camp Series Rear Control Arm Set (CMP-J-JL-RS4) for improved axle alignment and handling.

Enhanced Stability and Control

Lifting your Jeep affects the rear axle position, causing it to shift off-center. The Camp Series Rear Track Bar corrects this by bringing the axle back to its ideal alignment, preventing uneven tire wear, steering inconsistencies, and suspension strain. This improves vehicle stability and ensures your Jeep tracks straight, reducing body roll when cornering or maneuvering off-road obstacles.

Two-Stage Powder Coating

Our dual-layer powder coating process ensures maximum corrosion resistance and long-lasting durability.

Zinc Primer Base Coat – Protects against rust and corrosion.

Durable Top Coat – Available in 10 custom colors to match your Jeep’s style while providing added durability.

Made in the USA

At CORE 4X4, we proudly manufacture our Camp Series Rear Track Bar in Orem, UT. By sourcing high-quality materials locally and maintaining strict quality control, we ensure our products meet the highest American manufacturing standards.

Straightforward Installation

Designed for simple, bolt-on installation using factory hardware, this track bar installs seamlessly. If your factory bolts are rusted or difficult to remove, we offer optional Grade 8 hardware kits separately for a hassle-free upgrade.


  • Vehicle Fitment: Jeep Wrangler JL 18+ – Designed to maintain axle alignment and improve stability after lifting your Jeep.

  • CORE Advantage: Fully adjustable to recenter the rear axle, reduce body roll, and enhance handling for a smoother, more controlled ride.

  • Adjustability: Accommodates lifts from 0–6”, ensuring proper suspension geometry and eliminating steering inconsistencies.

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

  • 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.

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 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

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 ! ! !

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.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

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.
