These control arms are a significant upgrade over factory components, offering improved strength, adjustability, and ride quality for both on-road stability and off-road flexibility.

What’s Included in the Kit?

  • Cruise Series Rear Lower Control Arms (CRS-J-JL-RL2)

Key Features and Benefits

  • Durable Steel Tubing Construction – Built from heavy-duty steel tubing, these control arms provide superior strength and long-lasting durability compared to factory components.
  • Precision Adjustability – Allows for accurate alignment correction and rear axle re-centering, accommodating lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Delivers a smoother ride, better articulation, and increased longevity over standard rubber bushings.
  • Improved Handling Ride Quality – Reduces rear-end instability and excessive suspension movement, enhancing both daily driving comfort and off-road capability.
  • Recommended Pairing for a Complete Suspension Solution – For full rear-end alignment control, pair with our Cruise Series Rear Upper Control Arms (CRS-J-JL-RU2).

Two-Stage Powder Coating for Maximum Protection

To maximize durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc Primer Base Coat – Provides a protective barrier against rust and environmental damage. Customizable Top Coat – Available in 10 color options, allowing you to personalize the look of your suspension components.

Made in the USA

Manufactured in Orem, UT, the Cruise Series Rear Lower Control Arms are built to the highest standards of American craftsmanship, ensuring superior durability and consistent, reliable performance in all driving conditions.

Optional Hardware Upgrade

Our Cruise Series Rear Lower Control Arms are designed for easy installation using factory hardware. However, for those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately to ensure a secure and hassle-free installation.

In Conclusion

Choosing the Cruise Series Rear Lower Control Arms means investing in a stronger, more responsive suspension upgrade that improves handling, rear axle stability, and overall driving performance.

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.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

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!

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 ! ! !

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.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.
