Product Details

The McLeod 560300 is a high-performance aluminum flywheel designed for 1955-1985 Chevrolet Small Block and 1970-1990 Big Block engines. Weighing just 15 pounds, this lightweight flywheel significantly reduces rotational mass compared to stock steel flywheels, allowing engines to rev faster and more freely—making it ideal for high-horsepower builds, supercharged, or turbocharged applications.

Key Features:

  • CNC machined from high-strength 6061 T6 aluminum for precision and durability
  • 153-tooth ring gear configuration for compatibility with standard starters
  • Replaceable steel friction plate for extended service life
  • 1045 steel hardened ring gear for reliable starter engagement
  • Zero balance (0 bal) design for neutral balance engines
  • 15-pound weight dramatically improves throttle response and acceleration

This flywheel is engineered for racing and performance applications where rapid RPM changes and reduced drivetrain weight are critical. The replaceable friction surface ensures you can rebuild rather than replace, making it a cost-effective long-term solution for serious enthusiasts and racers.

NOTE:

CENTERBORE/CRANK BOSS: Because of standard variances in OEM and Aftermarket manufacturing tolerances, the flywheel to crankshaft boss fit may have variations from slip-fit to slight interference. Interference at the crankshaft “boss” can be corrected by heating the flywheel to temporarily to expand the center bore for correct mounting. Caution, flywheel will be hot, handle with care.
