Heavy-Duty Performance for Towing Hauling

Maximize the strength and durability of your Dodge Ram 3500 (2003–2007) with the Tow Series Adjustable Front Lower Control Arms. Specifically engineered for heavy-duty applications like towing and hauling, these control arms provide exceptional stability, strength, and adjustability for the toughest driving conditions. Whether you're tackling rough job sites or hauling heavy loads, these control arms are built to handle it all.

Key Features Benefits

  • Heavy-duty DOM tubing construction – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, these control arms offer unmatched strength and durability for high-load applications.
  • Rock Jock 4x4 Johnny Joints at both ends – Features fully greaseable and rebuildable joints, delivering increased articulation, long-term reliability, and reduced wear on suspension components.
  • Effortless adjustability for precision alignment – Designed to correct wheel centering and caster for lifts from 0 to 6 inches. Threaded with left- and right-hand threads, allowing on-the-truck adjustments without removal. When paired with Tow Series Adjustable Upper Control Arms, these provide full suspension control and optimization. For lifts beyond 6 inches, contact us for additional options.
  • Recommended pairing – Optimize your suspension setup by adding the Tow Series Adjustable Upper Control Arms (TOW-D-35-2003-FU2) for full caster adjustment and wheel centering control.

Two-Stage Powder Coating for Maximum Protection

To ensure long-lasting durability, our control arms undergo a two-stage powder coating process. A zinc primer base coat enhances rust and corrosion resistance, while the durable topcoat, available in 10 color options, allows you to personalize your build.

Made in the USA

Proudly designed, engineered, and manufactured in Orem, UT, ensuring top-tier craftsmanship, strict quality control, and long-term reliability.

Optional Hardware Upgrade

Installs using factory hardware, but for a smoother installation and enhanced durability, we offer an optional Grade 8 hardware kit with a cam bolt delete, available separately.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

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 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!

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.
