2003–2025 Dodge Ram 3500 5.7L/6.4L/6.7L Diesel & Hemi Engines

Part #: DR3500CA

Overview

The Timbren Rear Suspension Enhancement System (SES) is engineered to improve the suspension performance of your Dodge Ram 3500, spanning model years 2003 through 2025. Designed specifically for trucks equipped with 5.7L Hemi, 6.4L 392, 5.9L Diesel, and 6.7L Diesel engines, this system enhances load handling, reduces trailer sway, and improves overall ride stability. Ideal for Ram owners who frequently haul heavy loads or tow trailers, the Timbren SES provides a safer, more controlled driving experience without compromising ride comfort.

Unlike traditional suspension upgrades, the Timbren SES uses advanced rubber cushions that absorb road shocks and automatically adjust to varying loads and road conditions. This ensures consistent suspension support whether your truck is empty or fully loaded, delivering peace of mind and improved vehicle control in all driving scenarios.

Construction & Design

The Timbren Rear Suspension Enhancement System features high-quality rubber springs engineered to provide progressive resistance under load. These rubber cushions are precision-molded to absorb and dissipate energy from road impacts and heavy payloads, reducing stress on the factory suspension components. The system’s robust design ensures long-lasting durability, resisting wear from repeated compression cycles and exposure to the elements.

Installation brackets and hardware are crafted from corrosion-resistant steel, ensuring a secure fit and reliable performance over time. The bolt-on design preserves the integrity of your vehicle’s frame and suspension, requiring no permanent modifications or drilling.

Installation & Fitment

Installing the Timbren Rear Suspension Enhancement System is straightforward and user-friendly. The kit bolts directly onto the vehicle’s existing suspension mounting points without the need for drilling or routing airlines. This allows for a quick installation process that can typically be completed in minutes using basic hand tools.
