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.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

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!!

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Excellent, strong, and durable products—perfect for both on-road and off-road applications. The customer service is outstanding—friendly, knowledgeable, and extremely helpful with understanding installation and ensuring I got exactly what I needed. I would definitely order again. Top-notch company with high-quality products made right here in the U.S.A.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

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!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.
