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.

What’s Included in the Kit?

  • Cruise Series Rear Upper Control Arms (CRS-J-WK-RU2)

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.

In Conclusion

The Cruise Series Rear Upper Control Arms are an essential upgrade for any lifted Jeep Grand Cherokee WK, delivering pinion angle correction, reduced vibrations, and enhanced rear-end stability. Pairing them with our Rear Lower Control Arms ensures total alignment control and superior handling performance.

Upgrade your Jeep today for a smoother, more controlled ride—on and off the road!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

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!

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.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

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!
