The Timbren SES suspension upgrade can be adapted to fit the rear suspension of
most heavy-duty Ford F600, F700 and F800 trucks equipped with leaf springs.
Each laser cut piece of steel is precision bent and powder-coated to ensure a
quality fit. The  hollow rubber springs deliver a progressive spring rate. In
other words, the more weight that pushes down on the rubber springs the harder
they work to prevent rear end sag, and help stabilize the load.
