Flywheel Ring Gear

Part Number : ZA-521

Original Equipment (OE) Part Interchange

AMC: 3214033

Features & Benefits

The ring gear has teeth which engage with the starter motor allowing the engine to crank over and start. Repeated engagement with the starter results in worn or broken ring gear teeth. Once this is diagnosed, the ring gear must be replaced. ATP ring gears are designed to fit and function just like the original part to ensure durability and long life.
  • Manufactured to meet or exceed original equipment specs
  • Eliminates grinding from damaged teeth
  • Increases starter drive life
