This kit includes 2 components, each built and powder-coated in-house.
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.
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.
