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.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

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.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

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

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!
