Product Details

Performance Boost

Upgrade your on-road stability and off-road capability with our Cruise Series Rear Lower Control Arms, designed specifically for Jeep Grand Cherokee WK model years 2005-2010. These control arms outperform factory components, providing superior durability, strength, and precision alignment for a smoother, more controlled driving experience.

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built to withstand harsh conditions and deliver long-lasting performance.
  • Fully Adjustable Design – Allows for pinion angle correction and rear axle re-centering, accommodating lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Provides enhanced responsiveness, reduced vibrations, and better articulation.
  • Recommended Pairing – For a complete rear suspension solution, pair with our Cruise Series Rear Upper Control Arms (CRS-J-WK-RU2) to fully correct alignment and optimize handling.

Optimized Rear Suspension Performance

Lifting your Jeep can misalign the rear axle, cause excessive tire wear, and create instability. Our adjustable Rear Lower Control Arms provide the necessary strength and flexibility to correct pinion angles, re-center the axle, and improve handling. When combined with our Rear Upper Control Arms, you gain full control over rear suspension geometry, reducing unnecessary stress on your drivetrain and enhancing overall ride quality.

Two-Stage Powder Coating for Maximum Durability

To ensure long-term performance and corrosion resistance, all components undergo a two-stage powder coating process: Zinc primer base coat – Provides rust protection. Durable top coat – Available in 10 colors, allowing you to personalize your suspension.

Made in the USA

Proudly manufactured in Orem, UT, using locally sourced materials to meet the highest quality standards.

Optional Hardware Upgrade

Designed for easy installation using factory hardware. If you're dealing with rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, for a hassle-free install.

Upgrade today and experience superior handling, durability, and off-road confidence!


  • Vehicle Fitment: Jeep Grand Cherokee WK 05-10 – Improves rear axle alignment, restores suspension geometry, and enhances stability for better on-road handling and off-road performance.

  • CORE Advantage: Helps correct pinion angle and re-centers the axle, reducing driveline stress and tire wear while improving rear suspension stability for a smoother and more controlled ride.

  • Adjustability: Fully adjustable design accommodates lift heights from 0 to 6 inches, allowing precise alignment correction and axle re-centering for optimal performance.

  • Construction: Built from heavy-duty steel tubing with tapered polyurethane bushings for enhanced durability, improved responsiveness, and long-term reliability over factory components.

  • 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.

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

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!

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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!!
