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.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

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.
