Unmatched Flexibility Durability

Upgrade your Ford Bronco (2021-Present) with the Aluminum Series Rear Upper Control Arms, designed for maximum off-road articulation, precise axle alignment, and long-term durability. This advanced suspension upgrade enhances both on-road stability and off-road capability, offering a substantial improvement over factory components.

What’s Included

  • Aluminum Series Rear Upper Control Arms (AL-F-BR-2021-RU2)

Key Features Benefits

  • Precision-engineered 7075 aluminum – Constructed from 1.75” OD 7075 aluminum, these control arms provide exceptional strength while remaining lightweight, significantly outperforming stock components.
  • Extreme off-road articulation – Johnny Joints at both ends maximize suspension travel, reduce binding, and improve axle control, enhancing ride comfort and durability.
  • Fully adjustable for lifted vehicles – Designed to accommodate lifts from 0 to 6 inches, these control arms allow precise axle centering and pinion angle adjustments, optimizing suspension geometry for better handling.
  • Machined wrench flats for easy adjustments – The left- and right-hand threaded bodies simplify on-the-vehicle fine-tuning, eliminating the need for removal during suspension alignment.

Superior Lightweight Construction with 'Memory'

Fabricated from high-strength 7075 aluminum, these control arms provide a durable yet lightweight alternative to steel. Unlike traditional materials, 7075 aluminum features a "memory" effect, allowing it to return to its original shape after impact, ensuring long-lasting structural integrity.

Customizable Powder Coating

Enhance your Bronco’s aesthetics with our customizable powder coating options. Choose the raw aluminum finish for a sleek, high-performance look, or select from ten vibrant colors to match your build.

Proudly Made in the USA

Our Aluminum Series Rear Upper Control Arms are proudly designed and manufactured in the USA, ensuring strict quality control, superior craftsmanship, and premium materials. Choosing CORE 4X4 means supporting American innovation and excellence.

Optional Hardware Upgrade

Designed for seamless installation using factory hardware, these control arms provide a straightforward upgrade. If you're dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a hassle-free installation.

In Conclusion

The Aluminum Series Rear Upper Control Arms provide superior strength, extreme articulation, and precise adjustability, making them the ultimate off-road upgrade for your Ford Bronco. Whether tackling rugged trails or maintaining highway stability, these control arms deliver unmatched durability and control.

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.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

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.

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.

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.
