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.

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.

Upgrade today and experience the next level of suspension performance!

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.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!
