.531 ID Distributor Gear Melonized - Ford

The .531 ID Distributor Gear Melonized - Ford by COMP CAMS is a precision engine component engineered for small block Ford applications requiring reliable ignition timing control. This distributor gear serves as the critical link between the crankshaft and distributor shaft, ensuring synchronized firing sequences essential to engine performance and longevity. Built for mechanics, engine builders, and Ford enthusiasts who demand OEM-quality replacement parts, this melonized iron gear withstands high RPM operation and thermal cycling without degradation.

Constructed from iron and finished with a black melanized coating, the .531 ID shaft distributor gear resists corrosion and wear while maintaining tight tolerances critical for timing accuracy. The melanized surface treatment provides superior hardness and wear resistance compared to bare iron, extending component lifespan under sustained engine stress. At 0.18 lbs and compact dimensions of 3.55 x 1.3 x 6.35 inches, this gear integrates seamlessly into small block Ford engine bays. COMP CAMS' engineering ensures proper tooth engagement and minimal backlash, which directly translates to stable idle quality, responsive throttle control, and predictable spark advance characteristics.

This distributor gear is ideal for stock restorations, street engine rebuilds, and performance applications where original equipment specifications are required or preferred. Installation is straightforward for experienced mechanics familiar with small block Ford distributor assembly; proper alignment of the gear with the camshaft drive gear is essential to prevent timing drift and component premature wear. Purchase this replacement gear when rebuilding distributors, addressing worn timing components, or performing complete engine restoration on Ford 289, 302, 351W, and related small block platforms.
