A Hays lightweight aluminum flywheel gives you the opportunity to upgrade your stock flywheel to a stronger and safer SFI-certified version. It delivers faster throttle response and quicker acceleration providing additional horsepower to the wheels while offering overall weight reduction and excellent heat dissipation.

This weight reduction provides reduced clutch wear and stress on your engine. It also provides smoother, faster gear shifting along with easier braking and better slowing due to its reduced rotational mass. The reduced rotating mass could also offer the potential for increased fuel economy. All Hays lightweight aluminum flywheels are engineered to handle extreme duty applications along with being designed to take the punishment of today’s high horsepower street, race, and off-road engines.

NOTE: When choosing a flywheel take note that a heavy flywheel stores more energy as it spins than a light flywheel. If you have a heavy car combination that requires more power (or inertia) to make it launch without bogging the engine, you will want a heavier flywheel. Remember that a heavier flywheel will be slower to accelerate through the gears where a lighter flywheel creates less inertia at launch but will accelerate faster through the gears.
