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!

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 wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

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👌🏽

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.
