Detailed Description

The Pioneer Cables FRG-204A ring gear is used on the flywheel where the starter drive engages to crank the engine. Over time, repeated starting can wear the teeth or break sections of the ring gear, leading to hard-start or no-crank conditions. This replacement ring gear is made to match the original fit and function so the starter can engage the flywheel correctly again. For Chevrolet and GMC vehicles requiring a 204-tooth clutch flywheel ring gear, FRG-204A provides the dimensions and tooth count needed for proper service.

This part cross-references AMS Automotive 4455 for the same application.
