Enhanced Vehicle Stability

Eliminate rear-end wandering and axle misalignment with the Cruise Series Rear Track Bar, engineered specifically for Jeep Grand Cherokee WK models from 2005-2010. This track bar ensures your axle remains perfectly centered, improving both on-road stability and off-road articulation. Designed to handle aggressive terrain, lifted suspensions, and high-speed handling, this heavy-duty upgrade is essential for maintaining tight, controlled suspension geometry.

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built with high-strength materials to handle extreme loads and harsh conditions.
  • Adjustable for Perfect Axle Alignment – Corrects axle shift after lifting your vehicle, working with lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) while ensuring a tight, responsive ride.
  • Greaseable and Rebuildable Joints – Allows for easy maintenance and extended service life, keeping your suspension performing at its best.

Enhanced Stability and Handling

A misaligned rear axle can lead to unpredictable handling, increased tire wear, and drivetrain stress. Our adjustable rear track bar eliminates axle shift, keeping your suspension geometry in check for smooth, predictable performance at all speeds and terrains. Whether you're tackling rocky trails or cruising on the highway, this track bar keeps your WK planted and controlled.

Recommended Pairing

Combine with the Cruise Series Rear Control Arm Set (CRS-J-WK-RS4) for a fully optimized rear suspension system.

Two-Stage Powder Coating for Maximum Durability

All components undergo a two-stage powder coating process for corrosion resistance and long-term durability. A zinc primer base coat provides superior rust protection, while the durable top coat—available in 10 color options—adds resilience and a custom look.

Made in the USA

Manufactured in Orem, UT, using high-quality, locally sourced materials to ensure precision, durability, and peak performance.

Optional Hardware Upgrade

Designed for easy installation using factory hardware. If you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a seamless installation.


  • Vehicle Fitment: Jeep Grand Cherokee WK 05-10 – Prevents rear-end wandering, axle misalignment, and instability by keeping your rear axle centered, improving both on-road stability and off-road articulation.

  • CORE Advantage: Corrects axle shift, restores suspension geometry, and eliminates driveline stress, providing a smoother, more predictable ride on both highways and rugged terrains.

  • Adjustability: Fully adjustable for lifts from 0 to 6 inches, ensuring perfect axle alignment and optimized suspension geometry to enhance overall stability and handling.

  • Construction: Built with heavy-duty steel construction and tapered polyurethane bushings to reduce NVH (Noise, Vibration, Harshness) while providing a tight, responsive, and durable ride.

  • 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.

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
