SunCoast A1-BFP-AZB Billet Flex Plate | 2001-2004 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LB7

This replaces the factory flywheel/flexplate with an improved billet steel one-piece design and eliminates the heavy cast iron and the weak stamped steel flex plate. This is a must with the high torque in conjunction with a better-designed torque converter that can transfer the torque with no slip. The flex plate is bolted to the crankshaft and then the converter is bolted to flex plate. The torque from the motor is transferred to the flex plate, then goes from the flex plate to the torque converter and finally to the in- put shaft in the transmission. With increased torque from the engine, it can crack and/or rip the center out of a stock flex plate.
