2007-2012 Dodge 6.7L Cummins diesel. The DPC Heavy-Duty Flex Plate features a stamped steel construction and is double the thickness of the factory flex plate in your truck. This Flex Plate has a 29.1 SFI approval and is geared towards a budged minded build, or anyone that doesn't plan to push the limits of their truck. This stamped flex plate is a very affordable alternative to the billet flex plates out there for those that aren't racing.
