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.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽
