Performance and Comfort

Upgrade your Jeep Wrangler TJ or LJ with the Cruise Series Rear Control Arm Set, designed to enhance both off-road capability and on-road comfort. This set includes adjustable upper and lower rear control arms, significantly improving axle alignment, suspension articulation, and overall drivability.

Built to withstand rugged trails and highway conditions alike, this upgrade ensures long-term durability and superior performance over factory components.

What’s Included in the Kit?

  • Cruise Series Rear Upper Control Arms (CRS-J-TJLJ-RU2)
  • Cruise Series Rear Lower Control Arms (CRS-J-TJLJ-RL2)

Key Features and Benefits

  • Enhanced Strength and Durability – Built from heavy-duty steel tubing, these control arms provide superior strength over factory components.
  • Precision Adjustability – Fully adjustable to accommodate 0 to 6 inches of lift, ensuring proper axle centering and pinion angle correction.
  • Optimized Drivability – Corrects rear axle misalignment and improves handling, reducing tire wear and suspension stress.
  • Recommended Pairing – For complete rear-end alignment and full pinion angle control, pair with our Cruise Series Rear Track Bar (CRS-J-TJLJ-RTB1).

Full Rear Suspension Control

When lifting your Jeep, improper pinion angles and axle misalignment can lead to driveline vibrations and handling instability. This rear control arm set allows for precise axle centering and pinion angle adjustments, eliminating these common suspension issues.

When paired with our Rear Track Bar, this combination ensures optimal handling and maximum rear-end stability in all driving conditions.

Two-Stage Powder Coating

Each control arm is coated with a two-stage powder coating process for maximum durability: Zinc primer base coat provides superior corrosion resistance. Top coat available in 10 color options, allowing you to personalize the look of your suspension components.

Made in the USA

All Cruise Series components are proudly manufactured in Orem, UT, ensuring the highest quality craftsmanship while supporting American manufacturing.

Optional Hardware Upgrade

  • Our Rear Control Arm Set is designed for easy installation using factory hardware.
  • For those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately, to make the installation process seamless.

In Conclusion

Upgrading to the Cruise Series Rear Control Arm Set gives you the strength, adjustability, and precision needed for optimal performance.

Whether you’re tackling tough trails or cruising on the highway, these control arms will correct pinion angle, recenter the rear axle, and provide enhanced drivability.

Pair with our Cruise Series Rear Track Bar for complete rear suspension control and enjoy a smoother, more stable ride.

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 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 purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …

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!!!

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.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.
