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.

What’s Included in the Kit?

  • Tow Series Adjustable Front Upper Control Arms (TOW-D-25-2003-FU2)
  • Tow Series Adjustable Front Lower Control Arms (TOW-D-25-2003-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 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!

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.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

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!

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.
