The flywheel and clutch for most automatic transmissions is simply a stamped-steel disc with a ring gear located at the outer edge for engagement with the starter’s pinion gear. With this type of flywheel, the torque converter has no ring gear. Some cars use a more modest flywheel known as a flexplate, which is all that’s needed because the torque converter itself has a ring gear located on its outer edge.

The flexplate mounts to the engine's crankshaft and also serves as a mounting location for the torque converter. The flexplate transmits engine torque to the torque converter housing. The flexplate’s ring gear also serves as an engagement point for the pinion of the starter motor when cranking the engine. Because of the lightweight design of the flexplate, it does not help to smooth out power pulses from the engine like the flywheel does on a car with a manual transmission. On cars with automatic transmissions, the torque converter provides this function.

PRW flexplates raise the bar in the high performance industry. The combination of top quality and reasonable pricing sets new standards. There are three series of fklexplates. Gold Series Flexplates are engineered to handle extreme duty applications and designed to take the punishment of today’s high horsepower engines. The thick centerplate provides a solid foundation for these new designs. Ring gears are precision welded to meet SFI specifications, utilizing robotic machinery and cold-welding process. PRW flexplates are engineered for excellence and are rigorously inspected throughout the manufacturing cycle to ensure that our customers receive the quality that they have come to expect from PRW products.

Platinum Series Flexplates are engineered to handle extreme duty applications and designed to take the punishment of today’s high horsepower engines. The 4mm thick centerplate provides a solid foundation for these new designs. Ring gears are precision welded to meet SFI specifications, utilizing robotic machinery and cold-welding process. PRW flexplates are engineered for excellence and are rigorously inspected throughout the manufacturing cycle to ensure that our customers receive the quality that they have come to expect from PRW products.
