GMC I1000 Clutch Systems

Vehicles with manual transmissions have a flywheel. The Flywheel is where the clutch assembly is mounted. It provides a smooth friction surface for the clutch disk. Flywheels also have teeth for the starter. Flywheels can crack, break, or break starter teeth. Once a damaged flywheel is diagnosed, a new replacement is the best route to go. ATP flywheels provide fit and function just like the original part to ensure durability and long life.
