Flywheel hot spots can cause chatter. Resurfacing a flywheel doesn’t always remove hot spots. The flywheel may look shiny and pretty, but the hot spots will often still be there. Service the System by replacing the flywheel and the clutch set at the same time. All flywheels come with a new ring gear.

Product Features:

• Casting process closely monitored to ensure uniform density and balance retention
• Eliminates chance of chatter due to hot spots not always removed by resurfacing
• New ring gear ensures positive starter engagement
• Engineered to properly fit the intended application with no modifications
