This Sun Coast 618 - BFP Billet Flex Plate is a game - changer for your 1994 - 2007 Dodge 5.9L Cummins truck. It's essential for transferring power to the ground effectively. When your Cummins engine's high torque combines with a well - designed torque converter, this flex plate ensures no slip during torque transfer. It bolts to the crankshaft, and then the converter attaches to it. The engine's torque travels through the flex plate to the converter and then to the transmission's input shaft. With increased engine torque and no converter slip, a stock flex plate can crack or tear, but this billet flex plate is up to the challenge. The Sun Coast billet flywheels are CNC machined from a forging for strength, with reliefs machined between the converter mounting area and the crank flange for flexibility. Part Number: 618 - BFP. Features: Exceeds 29.3 SFI Specifications, Replaces Factory Flex Plate, Billet Construction. Notes: A SFI certified flywheel flex plate is needed for drag racing vehicles with specific speed requirements. The SFI specification for diesel automatic transmission flexplates changed in 2008. The flex plate material can't be stamped metal, and it must be replaced every three years to meet the 29.3 SFI specification.

Using this flex plate is straightforward. First, make sure your truck is turned off and in a safe, stable position. Bolt the flex plate securely to the crankshaft of your 1994 - 2007 Dodge 5.9L Cummins engine. Then, attach the torque converter to the flex plate. That's it, and you're ready to transfer power effectively. When it comes to maintenance, keep an eye on the flex plate for any signs of damage or wear. Since it must be replaced every three years to meet the SFI 29.3 specification, mark your calendar so you don't forget. Also, if you're using your truck for drag racing, ensure it meets the speed - related requirements for SFI certification. And always remember, don't use a stamped - metal flex plate as it won't meet the new rules.
