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.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

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👌🏽
