The Ford F-650 was a variant of the 2nd Gen F-Series Super Duty that was introduced for the 2008 model year. The F-650 Super Duty was a heavy-duty truck that was only built in a cab-chassis body style, in standard, extended, and crew cab configurations. Depending on the customers needs, these cab-chassis could be fitted with a range of attachments, even including pickup beds. Two diesel engine options were offered, the Caterpillar 3126 (7.2L I6), which was last available in 2009), and the Cummins ISB (6.7L I6). These engines were paired to manual or automatic transmission options with drive sent to the dual rear wheels. Production of the 2nd Gen F-650 ended in 2010, when it was replaced by the 3rd Gen Ford F-650 Super Duty.
