Timbren Helper Spring Kit (MPN: FRTTSDE)

Enhance your Ford F-450 and F-550 suspension with advanced rubber springs.

The Timbren Helper Spring Kit is designed specifically for the rear suspension of Ford F-450 and F-550 cab chassis trucks. This suspension enhancement system utilizes hollow rubber springs that provide a progressive spring rate, effectively preventing rear end sag when carrying heavy loads or towing trailers. Each component is precision engineered, featuring laser cut steel that is powder-coated for durability and a quality fit.

This kit replaces the jounce stop on the frame, ensuring optimal ride quality whether the vehicle is loaded or unloaded. The unique design of the hollow rubber springs allows them to automatically adjust to varying weights, maintaining a level vehicle stance at all times. With a load capacity of 8000 pounds, this system is suitable for applications requiring maximum stability, such as those involving slide-in campers or salt spreaders.

The Timbren Helper Spring Kit not only eliminates vehicle squatting and sagging but also cushions road shocks and improves overall handling. It is important to note that while this upgrade increases the spring rate, it does not alter the Gross Vehicle Weight Rating (GVWR) set by the manufacturer. Proper installation and maintenance will ensure the longevity and effectiveness of the suspension enhancement.
