Complete Axle Centering Stability Solution

Upgrade your Jeep Wrangler JK’s suspension performance with the Cruise Series Track Bar Kit, an essential upgrade for any lifted Jeep. This kit includes both our front and rear adjustable track bars, ensuring precise axle centering, enhanced handling, and improved stability on and off the road.

When a Jeep is lifted, axle shift and misalignment can cause handling issues, suspension stress, and even contribute to death wobble. The Cruise Series Track Bar Kit corrects these problems, keeping your Jeep tracking straight, reducing body roll, and improving steering response.

Key Features and Benefits

  • Superior Axle Alignment – Adjustability allows for precise centering of the axle, correcting the natural shift that occurs when lifting a Jeep.
  • Reduces Steering Instability Body Roll – Helps minimize wandering, following ruts in the road, and steering inconsistencies for a more controlled ride.
  • Solves Suspension Stress Issues – Reduces excessive wear on bushings, ball joints, and steering components, ensuring longer part life and better overall performance.
  • Heavy-Duty DOM Tubing Construction – Built from 1.5” OD 5/16” wall DOM steel tubing for maximum strength and longevity.
  • Tapered Polyurethane Bushings – Absorb road vibrations while providing durability and responsiveness, outperforming standard rubber bushings.
  • Compatible with Lifts from 0 to 6 Inches – Adjustable design allows for precise axle recentering without needing additional modifications. For lifts over 6 inches, contact us for custom solutions.

Durable Two-Stage Powder Coating

Our track bars undergo a two-stage powder coating process for maximum durability and corrosion resistance: Zinc primer base coat – Provides superior rust protection. Durable top coat – Available in 10 color options for personalization.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Track Bar Kit is designed to meet the highest American quality standards, ensuring long-lasting performance.

Effortless Installation

Designed for direct bolt-on installation using factory hardware. If dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a seamless upgrade.


Each rebuild kit includes all necessary components to replace and restore wearable parts.

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!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!
