ATP Parts ZA-532 Clutch Flywheel Ring Gear

Overview

ATP Parts ring gear ZA-532 is a clutch flywheel ring gear built for starter engagement and engine cranking. It is a direct-fit replacement for applications that use 148 teeth and a 12.41-inch outside diameter.

Key Features

• 148-tooth ring gear for starter motor engagement
• 12.41-inch outside diameter with 11.588-inch inside diameter
• 0.453-inch thickness for the specified flywheel setup
• 12-pitch flywheel specification

Detailed Description

The ATP Parts ZA-532 ring gear is engineered to replace a worn or damaged flywheel ring gear that no longer engages the starter correctly. Repeated cranking can wear or break the teeth, leading to starting problems. This ring gear is designed to fit and function like the original part, making it a practical replacement for Chevrolet Camaro, Chevrolet S10, GMC S15, Pontiac Firebird, and related applications that call for the same 148-tooth configuration. The ZA-532 part number is also useful when cross-checking service information and ordering the correct replacement.

This part cross-references Pioneer Automotive Industries FRG-148B and StrongArm 4488 for the same application.

Common Uses

• Restoring starter engagement when ring gear teeth are worn
• Replacing a broken flywheel ring gear that prevents cranking
• Correcting starter slip caused by damaged tooth profiles
• Addressing hard-start conditions tied to ring gear wear

Installation Notes

Verify tooth count, outside diameter, inside diameter, and flywheel pitch before installation. Confirm the application matches the 148-tooth, 12.41-inch specification listed for ZA-532. Professional installation is recommended to ensure proper alignment and starter engagement.

Quality Assurance

ATP Parts designs this ring gear to match the fit and function of the original component for dependable service life. The ZA-532 part number helps ensure the correct replacement is selected for the intended application.
