Complete Control for Towing Hauling

Take full control of your Dodge Ram 3500 (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.

What’s Included in the Kit?

  • Tow Series Adjustable Front Upper Control Arms (TOW-D-35-2003-FU2)
  • Tow Series Adjustable Front Lower Control Arms (TOW-D-35-2003-FL2)

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 positioning and drivability, pair with the Front Track Bar (D-35-2003-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-35-2003-FS4) is the ultimate upgrade for Ram 3500 (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 3500’s suspension for unmatched durability and stability!

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.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.
