Timbren Review: Ford F-550 Super Duty

Timbren KitEven super duty vehicles need some help with their suspension when hauling a heavy equipment trailer or other loads. A heavy haul can cause costly damage to even the toughest work truck’s suspension. A Timbren Leveling kit is a cheap and easily installable solution to expensive and dangerous problems down the road.

Ford Truck Timbren Kit

A 2010 Ford F-550 Super Duty was recently brought to us for this very reason. This truck has been in use for hauling heavy equipment with a trailer. Even with its heavy duty suspension, it was in need of some extra leveling support to reduce the amount of roll and sway experienced while driving. The Timbren FRSDD Bump Stop was installed as an answer to this issue.

Once the Timbren FRSDD helper springs were installed, there was an immediately noticeable difference. The OEM bump stops, while of a heavy duty quality, could not compare the new helper spring. By adding the Timbren spring, we had removed the several inches of slack that had existed between the leaf spring and the OEM bump stop. As a result the Timbren Kit provides cushioning and support to the suspension at all times, as opposed to the OEM Bump stop which only will provide relief when the spring is about to bottom out. By avoiding this shock to the leaf spring, years can be added to your truck’s suspension.
