This kit includes 3 components, each built and powder-coated in-house.
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.
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.
