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.

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.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

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.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!
