This kit includes 3 components, each built and powder-coated in-house.
The Ultimate Front-End Upgrade for Heavy-Duty Towing Hauling
Take full control of your Dodge Ram 2500 (2003–2007) with the Tow Series Adjustable Front Suspension Kit—a massive upgrade engineered specifically for towing, hauling, and extreme-duty applications. Factory suspension components simply can’t handle the added strain of heavy loads, leading to death wobble, wandering steering, and premature wear. This kit eliminates these issues by delivering unmatched strength, precision alignment, and rock-solid stability, making it an essential upgrade for any Ram owner who demands performance and reliability.
Key Features Benefits
- Eliminates Death Wobble Wandering Steering – By correcting caster and axle positioning, this kit locks in front-end stability, ensuring precise steering even under heavy towing loads.
- Maximum Strength for Towing Hauling – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, these components outperform factory parts by a wide margin, preventing bending, flexing, or failure under extreme conditions.
- Fully Adjustable for Perfect Alignment – Featuring left- and right-hand threads, all components can be adjusted on the truck without removal, making it easy to dial in precise caster and axle centering for improved handling and tire wear.
- Extreme Durability with Rock Jock 4x4 Johnny Joints – Unlike factory-style rubber or poly bushings that degrade under load, these greaseable, fully rebuildable Johnny Joints provide exceptional longevity, reduce wear on surrounding components, and eliminate bushing deflection for consistent performance.
Optional Inward Bend for Larger Tires
Running oversized tires? The optional inward bend upgrade allows for greater tire clearance, eliminating rubbing against control arms. This is a highly recommended upgrade for anyone experiencing steering limitations due to larger tires.
Two-Stage Powder Coating for Maximum Protection
Every component undergoes a two-stage powder coating process for exceptional durability and corrosion resistance. A zinc primer base coat ensures advanced rust protection, while a durable topcoat, available in 10 color options, allows you to match your truck’s style.
Made in the USA
Manufactured in Orem, UT, the Tow Series Front Suspension Kit is proudly built in the USA, ensuring strict quality control, superior craftsmanship, and long-term reliability.
Optional Hardware Upgrade with Cam Bolt Delete Kit
This kit 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.
