Hays heavy-duty flexplates for high performance and competition engines are constructed from a thicker-than-stock steel plate. This enables 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 flexplates can handle the force. These heavy-duty flexplates are supplied with a ring gear that is securely welded in place. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and SFI-certified under specification 29.1.

Hays steel flywheels are engineered to handle extreme-duty applications and designed to take the punishment of today's high-horsepower engines. They are CAD-engineered and precision CNC-machined to strict tolerances. Available in weights up to 50 lbs. for specialized applications, most Hays flywheels are drilled with both the Borg and Beck and Long-style clutch patterns. Upgrade to a precision-machined and engineered Hays billet steel flywheel. Features include: * SFI-approved--legal for use in racing classes that require SFI certification * CNC-machined from certified billet steel for maximum strength and durability * CAD-designed for optimum performance and reliability * Offered in internal, external, or neutral (zero) balanced versions * Available for a wide variety of engines Note: When choosing a flywheel, remember that a heavier flywheel stores more energy. A heavy car requires more power (or inertia) to launch without bogging the engine and needs a heavier flywheel. Lighter flywheels create less inertia at launch, but will accelerate faster through the gears.
