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.

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.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!
