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 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.
Features:
  • Thicker Than Stock Steel Plate
  • Ring Gear Securely Welded
  • Dual Bolt Patterns
  • Zinc-Dichromate Plated To Resist Corrosion
  • Withstands High Torque and RPM

About Hays

Drag racing's biggest stars have relied on Hays clutches since SEMA Hall of Famer Bill Hays decided back in 1958 that there had to be a way to build one that could stand up to racing's unimaginable power and torque. Now part of Holley Performance, Hays continues to develop complete clutch kits for an infinite number of high-performance applications, pressure plates for precise gear changes, clutch discs for smooth, chatter-free engagement, and flywheels and flexplates ideal for today's vehicles.
