Optimized Performance for Stability and Control

Eliminate axle misalignment, vibration, and rear-end instability with our Cruise Series Rear Upper Control Arms, designed specifically for Jeep Grand Cherokee WK models from 2005-2010. These control arms provide critical pinion angle correction, ensuring driveline stability, improved handling, and long-term durability—whether you're tackling tough trails or cruising on the highway.

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built to withstand harsh terrain and heavy loads while ensuring maximum durability.
  • Adjustable for Perfect Pinion Angle – Maintains proper alignment and driveline geometry for lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) while improving ride comfort and flexibility.
  • Greaseable and Rebuildable Joints – Designed for easy maintenance and long-term performance, keeping your suspension system in peak condition.
  • Recommended Pairing – Combine with Cruise Series Rear Lower Control Arms (CRS-J-WK-RL2) for complete rear-end alignment and axle recentering.

Precision Alignment and Drivability Enhancement

When lifting your Jeep Grand Cherokee WK, the rear pinion angle shifts, leading to driveline vibrations, premature wear, and unpredictable handling. These adjustable upper control arms allow precise pinion angle correction, ensuring smooth power delivery and reduced drivetrain stress. By pairing them with our Rear Lower Control Arms, you get full axle recentering and alignment correction, preventing excessive tire wear and instability.

Two-Stage Powder Coating for Maximum Durability

All control arms go through a two-stage powder coating process to ensure corrosion resistance and long-lasting durability: Zinc primer base coat – Provides enhanced rust protection. Durable top coat – Available in 10 color options, allowing you to customize your suspension’s look.

Made in the USA

Proudly manufactured in Orem, UT, using high-quality, locally sourced materials to guarantee precision, durability, and superior performance.

Optional Hardware Upgrade

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

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

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

Every product I have received from them has been nothing short of fantastic. Korby in Customer service went above and beyond to help me fix my own mistake. I cannot reccomend them enough.

Great long arm kit with everything else I needed as well! They worked with me to ensure that I was getting an upgraded components kit just like I wanted. Fast shipping with some of the best packaging that I have ever seen. Nothing was scratched or missing and this kit is even more impressive than the videos or website can show. Powder coating looks great with no issues. I would highly recommend CORE 4x4 to anyone looking for a great quality kit.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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!!!

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.
