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! 👍👍

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

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
