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.

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

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

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!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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!

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.
