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.

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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!

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 off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

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!

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!
