Please Note: Lightweight Steel flywheel for 8.50 in Twin Disc. Replacing your OEM flywheel with a light weight flywheel may cause gear noise or a vibration that may not be suitable for everyone. The lighter the flywheel the more gear noise will be produced. Depending on the application Clutch Masters usually recommends Steel flywheels rather than Aluminum flywheels since Aluminum flywheels will cause more gear noise.
