The Sun Coast 618-BFP Billet Flex Plate for your 1994-2007 Dodge 5.9L Cummins is a must have when it comes to putting power to the ground in your truck. The high torque of your Cummins in conjunction with a better-designed torque converter can transfer the torque with no slip. The flex plate is bolted to the crank shaft, then the converter is bolted to flex plate. The torque from your Cummins is transferred to the flex plate, from the flex plate to the torque converter then to your input shaft in the trans. With increased torque from the engine and no slip out of the converter, it can crack and/or rip the center out of a stock flex plate.
The Sun Coast billet flywheels are CNC machined from a forging for strength and reliefs are machined out between the converter mounting area and the crank flange to enable some flex. We designed our flexible billet flywheel with the understanding that it needs to flex but at the same time we added extra thickness to prevent cracking. We started with a better quality material and a better manufacturing process to make it stronger. Our flexible flywheel made or exceeded all the SFI specification 29.3 requirements for materials, mechanical properties, design and rotational integrity.
