Product Description

The Timbren FR350TTCC Rear Suspension Enhancement System is engineered for the 2005-2024 Ford F-350 Super Duty Cab & Chassis platform, providing exceptional rear-axle load support for commercial and heavy-duty applications. Designed to reduce sag, sway, and instability under substantial load, this kit uses progressive-rate hollow Aeon springs that engage only when needed.

Its bolt-on design ensures straightforward installation, making it one of the most efficient and durable solutions for severe-service fleet or work-truck environments.
