Unmatched Flexibility Durability

Upgrade your Ford Bronco (2021-Present) with the Aluminum Series Rear Lower Control Arms, built for superior off-road performance, increased articulation, and long-lasting durability. Designed to provide exceptional strength without added weight, these control arms offer a significant improvement over factory components, ensuring precise axle alignment and enhanced suspension travel for a smoother and more controlled ride on any terrain.

Key Features Benefits

  • Precision-Engineered 7075 Aluminum – Built from 1.75” OD 7075 Aluminum, these control arms provide the perfect balance of lightweight construction and extreme durability, outperforming factory components and other aftermarket options.
  • Exceptional Off-Road Articulation – Featuring Johnny Joints at both ends, these arms maximize articulation and shock absorption, improving your Bronco’s ability to tackle tough terrain with ease.
  • Adjustable for Lifted Vehicles – Designed to accommodate 0 to 6 inches of lift, these control arms allow for fine-tuning of axle centering and pinion angle, optimizing suspension geometry for better handling and stability.
  • Built for Easy Adjustments – Left- and right-hand threaded bodies and machined wrench flats make on-the-vehicle adjustments simple, allowing you to dial in your suspension settings with precision.

Superior Lightweight Construction with 'Memory'

The 7075 Aluminum construction provides a lightweight yet ultra-strong alternative to steel, giving you all the benefits of extreme strength without unnecessary weight. What sets 7075 Aluminum apart is its "memory" property, meaning it can regain its original shape after absorbing an impact, further extending the life of your control arms and preventing premature wear.

Customizable Powder Coating

Enhance the look of your Bronco’s suspension with our customizable powder coating options. You can choose from raw aluminum for a sleek, high-performance look or select from ten striking colors to match your vehicle’s build.

Proudly Made in the USA

Our Aluminum Series Rear Lower Control Arms are proudly manufactured in the USA with strict quality control standards to ensure maximum strength, precision, and durability. By choosing CORE 4X4, you’re supporting American craftsmanship and innovation.

Optional Hardware Upgrade

These control arms are designed for straightforward installation using factory hardware. However, if you're dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately to make the installation process as smooth as possible.

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.

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.

Great product, excellent customer service. I mistakingly ordered a track bar for the wrong year model and Korby helped me out by sending me the correct part that I needed no questions asked. I highly recommend.

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!

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

The quality and durability of the arms are the best. They are super heavy duty. And lifetime warranty is crazy
