1963 Ford 300 Flywheels

The ring gear has teeth which engage with the starter motor allowing the engine to crank over and start. Repeated engagement with the starter results in worn or broken ring gear teeth. Once this is diagnosed, the ring gear must be replaced. Pioneer ring gears are designed to fit and function just like the original part to ensure durability and long life.

Hays billet steel flywheels are manufactured from certified billet material that will not break up under the stress of high RPM and severe punishment of racing. Available in weights up to 50 pounds for specialized applications, most Hays flywheels are drilled with both the Borg and Beck and long-style clutch patterns. Hays flywheels are certified under SFI spec 1.1.

Hays heavy-duty flexplates for high performance and competition engines are constructed of a thicker than stock steel plate, enabling them to withstand the stress of high-stall torque converters and today’s high-RPM engines. While factory stock plates tend to crack around the crankshaft hub when punished under high torque and RPM conditions, the thicker Hays Flexplate handles the force. These H.D. flexplates are supplied with a ring gear that is securely welded in place and feature dual bolt patterns for flexibility in adapting to multiple transmission style torque converters. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.
