Improve the load-handling performance and ride stability of your 2003 Ford E-450 Super Duty with the Timbren FERSD Suspension Enhancement System. Designed for rear applications on motorhome, cutaway van, and stripped-chassis vehicles, this kit provides a 3,600-pound weight capacity to help reduce sagging, squatting, suspension settling, and trailer sway. Timbren’s rubber spring technology automatically adjusts to changing loads and road conditions while cushioning road shocks for more controlled handling.
Installation is straightforward and requires no drilling, airlines, fittings, or complicated adjustments. The Timbren FERSD kit bolts into place using basic hand tools, making it a practical upgrade for drivers who want improved suspension support without the maintenance associated with air-helper systems. Its maintenance-free design eliminates concerns about air leaks and does not require inflation or pressure monitoring.
As a leader in rubber spring technology since 1965, Timbren builds suspension solutions for dependable, long-term service. This rear suspension enhancement kit helps maintain vehicle ride height under load, improves handling, and provides added stability for work, travel, and towing applications. The kit is backed by Timbren’s lifetime warranty and is engineered to deliver trouble-free suspension support for the life of the vehicle.
