The Ultimate Front-End Upgrade for Heavy-Duty Towing Hauling

Maximize the performance of your Dodge Ram 3500 (2003–2007) with the Tow Series Adjustable Front Suspension Kit—a must-have upgrade engineered for towing, hauling, and extreme-duty applications. Stock suspension components struggle under heavy loads, leading to death wobble, wandering steering, and premature wear. This kit eliminates those issues by delivering increased strength, precision alignment, and rock-solid stability, ensuring superior control and durability under demanding conditions.

What’s Included in the Kit?

  • Adjustable Front Upper Control Arms (TOW-D-35-2003-FU2)
  • Adjustable Front Lower Control Arms (TOW-D-35-2003-FL2)
  • Adjustable Front Track Bar (D-35-2003-FTB1)

Key Features Benefits

  • Eliminates Death Wobble Wandering Steering – Corrects caster and axle positioning, ensuring precise steering and eliminating common front-end issues associated with heavy towing and hauling.
  • Maximum Strength for Heavy-Duty Applications – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, these control arms are designed to withstand high-load stress without bending or flexing.
  • Fully Adjustable for Precision Alignment – Designed with left- and right-hand threads, all components allow for on-the-truck adjustments without removal, ensuring caster and axle centering for optimal handling and tire wear.
  • Unmatched Durability with Rock Jock 4x4 Johnny Joints – Featuring greaseable, fully rebuildable Johnny Joints, these components reduce wear, eliminate bushing deflection, and provide long-term reliability in the toughest conditions.

Optional Inward Bend for Larger Tires

Running oversized tires? The optional inward bend upgrade provides extra clearance, preventing rubbing on the control arms. This is highly recommended for those running larger-than-stock tires to maintain full steering articulation.

Two-Stage Powder Coating for Maximum Protection

Each component undergoes a two-stage powder coating process to ensure long-lasting durability and corrosion resistance. A zinc primer base coat provides superior rust prevention, while a durable topcoat, available in 10 color options, allows you to match your truck’s build.

Made in the USA

Manufactured in Orem, UT, the Tow Series Front Suspension Kit is proudly built in the USA, ensuring top-tier craftsmanship, strict quality control, and unmatched reliability.

Optional Hardware Upgrade with Cam Bolt Delete Kit

This set installs using factory hardware, but for enhanced durability and easier installation, we offer an optional Grade 8 hardware kit with a cam bolt delete kit, available separately. The cam bolt delete kit eliminates weak factory cam bolts, preventing unwanted alignment shifts under load. It locks in proper alignment, ensuring stable, consistent performance under heavy towing and hauling conditions.

Final Thoughts

The Tow Series Adjustable Front Suspension Kit (TOW-D-35-2003-K5) is the ultimate upgrade for Ram 3500 owners who demand exceptional strength, precise alignment, and long-term durability. Whether you’re hauling trailers, towing heavy loads, or navigating demanding job sites, this kit provides the control and stability needed to tackle any challenge with confidence. Upgrade today and take full control of your Ram 3500’s suspension for unmatched performance and reliability!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

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!

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!
