Complete Control for Towing Hauling

Take full control of your Dodge Ram 2500 (2003–2007) suspension with the Tow Series Adjustable Front Control Arm Set. Designed for heavy-duty towing, hauling, and off-road durability, this set includes both adjustable front upper and lower control arms to provide maximum strength, stability, and alignment control. Whether you’re towing heavy loads or upgrading your truck’s performance, these control arms offer unmatched adjustability to fine-tune your axle position, caster, and pinion angle for optimal handling and drivability.

Key Features Benefits

  • Full Axle Alignment Control – Provides complete adjustability for axle positioning, pinion angle, and caster, ensuring proper suspension geometry and eliminating driveline vibrations.
  • Heavy-Duty DOM Tubing Construction – Built from 1.75” OD DOM tubing with a 5/16” wall thickness, these control arms offer superior 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 suspension wear.
  • Effortless Adjustability – Threaded with left- and right-hand threads, allowing for on-the-truck adjustments without removal. Accommodates lifts from 0 to 6 inches.

Recommended Pairing

For complete control over axle location and drivability, pair with the Front Track Bar (D-25-2003-FTB1).

Optional Inward Bend for Larger Tires

For trucks running larger tires that experience rubbing against the control arms, we offer an optional inward bend upgrade. This design modification provides additional clearance while maintaining full strength and stability. If your tires currently rub, we strongly recommend selecting this upgrade for a better fit and improved articulation.

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 provides advanced rust and corrosion resistance, followed by a durable topcoat available in 10 color options, allowing 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 with Cam Bolt Delete Kit

This set 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 kit, available separately. This upgrade eliminates weak factory cam bolts, ensuring proper alignment retention and preventing unwanted shifting under load—a crucial improvement for vehicles that tow or haul heavy loads regularly.

Conclusion

The Tow Series Adjustable Front Control Arm Set (TOW-D-25-2003-FS4) is the ultimate upgrade for Ram 2500 (2003–2007) owners looking for superior strength, adjustability, and long-term performance in heavy-hauling and towing applications. Upgrade today and take full control of your Ram 2500’s suspension for unmatched durability and stability!

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!

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.
