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.

Overview

Upgrade your stock flywheel to a Hays SFI-approved aluminum flywheel. Each flywheel is precision machined and engineered to handle extreme duty applications along with being designed to take the punishment of today's high horsepower street, off-road, and race engines.

Features:

  • SFI-approved – legal for use in racing classes that require SFI certification
  • 6061-T6 billet aluminum construction for weight reduction and excellent heat dissipation
  • CAD designed to provide optimum performance and reliability
