Cruise Series Rear Track Bar – Compatible with Jeep Wrangler JK (2007-2018) (CRS-J-JK-RTB1)

Enhanced Stability Suspension Control

Improve the handling, alignment, and overall drivability of your Jeep Wrangler JK with the Cruise Series Rear Track Bar. Designed to eliminate rear axle shift and maintain proper suspension geometry, this track bar ensures a more controlled and stable ride—whether you're navigating rugged trails or daily driving on the highway. If you're experiencing rear-end wandering, uneven tire wear, or instability caused by suspension modifications, upgrading to an adjustable rear track bar is a crucial step in fine-tuning your Jeep’s performance.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.5" OD .313 Wall DOM tubing for maximum durability and off-road performance.
  • Adjustability for Lifted Vehicles – Designed to recenter your rear axle and correct misalignment, accommodating lifts from 0 to 6 inches.
  • Reduces Rear Axle Shift Improves Handling – Prevents side-to-side axle movement, enhancing drivability, stability, and suspension control.
  • Premium Polyurethane Bushings – High-grade polyurethane bushings provide better responsiveness and longevity compared to rubber alternatives.
  • Helps Address Rear-End Instability – Ideal for correcting rear-end wandering, improving steering feel, and reducing suspension stress.
  • For lifts beyond 6 inches, contact us for custom solutions.

Durable Two-Stage Powder Coating

To maximize longevity and corrosion resistance, all track bars undergo a two-stage powder coating process: Zinc primer base coat – Provides superior rust protection in extreme conditions. Durable top coat – Available in 10 color options to match your Jeep’s style.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Rear Track Bar is built to the highest American standards, ensuring quality, reliability, and performance.

Effortless Installation

Designed for simple bolt-on installation, this track bar works with factory hardware. If dealing with rusted or worn-out bolts, we offer optional Grade 8 hardware kits separately for a seamless upgrade.

  • Vehicle Fitment: Jeep Wrangler JK 07-18 – Reduces rear axle shift, improves alignment, and enhances stability for better handling on and off-road. Essential for lifted Jeeps to maintain precise suspension geometry.

  • CORE Advantage: Adjustable design re-centers the rear axle after lifting, minimizing side-to-side movement for improved drivability, reduced suspension stress, and a smoother ride.

  • Adjustability: Designed to accommodate lifts from 0 to 6 inches, allowing for fine-tuned axle positioning and alignment correction. For lifts beyond 6 inches, contact us for custom solutions.

  • Construction: Built from 1.5” OD 5/16” wall DOM tubing for maximum strength. High-quality polyurethane bushings provide better responsiveness, vibration dampening, and long-term durability over factory rubber bushings.

  • 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.

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!

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.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

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.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!
