Performance and Stability Upgrade

Enhance your on-road stability and off-road capability with our Cruise Series Rear Lower Control Arms, specifically designed for Jeep Grand Cherokee WJ models from 1999-2004. These control arms significantly outperform factory components, providing increased strength, durability, and adjustability for a smoother and more controlled ride.

Key Features and Benefits

  • Enhanced Strength Durability – Heavy-duty steel tubing construction offers superior resistance to bending and wear.
  • Optimized Adjustability – Designed to accommodate 0 to 6 inches of lift, ensuring precise pinion angle correction and rear axle re-centering.
  • Advanced Bushings – Equipped with tapered polyurethane bushings at both ends, delivering improved responsiveness and reduced vibrations.
  • Recommended Pairing – For full alignment correction and rear axle recentering, pair with our Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) or A-Arm Spacer for enhanced performance.

Precision Adjustability for Pinion Angle Correction

Proper pinion angle alignment is critical for eliminating driveline vibrations and preventing premature wear on drivetrain components. These fully adjustable control arms allow you to fine-tune your suspension geometry, ensuring a smooth ride and optimized drivetrain performance.

Two-Stage Powder Coating for Maximum Durability

To ensure long-lasting protection, our control arms undergo a two-stage powder coating process: Zinc primer base coat for exceptional corrosion resistance. Durable top coat available in 10 color options for a personalized look.

Made in the USA

Proudly manufactured in Orem, UT, using locally sourced materials. We maintain strict quality control standards to ensure our products outperform and outlast the competition.

Optional Hardware Upgrade

Our Rear Lower Control Arms are designed for easy installation using factory hardware. However, if you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to simplify the installation process.


  • Vehicle Fitment: Jeep Grand Cherokee WJ 99-04 – Improves rear axle alignment, eliminates driveline vibrations, and enhances overall vehicle stability, ensuring smooth handling on both highways and off-road terrain.

  • CORE Advantage: Fully adjustable design allows precise pinion angle correction and rear axle re-centering, reducing driveline stress and improving handling for a more controlled ride.

  • Adjustability: Designed for lifts ranging from 0 to 6 inches, these control arms ensure proper suspension geometry and driveline alignment, optimizing performance on various terrains.

  • Construction: Built from heavy-duty steel tubing with tapered polyurethane bushings for maximum 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.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

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! 👍👍

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.
