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.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

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!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

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!
