Distributor Gears

The distributor gear is the critical link between your camshaft and the distributor, translating cam rotation into precise ignition timing. A properly matched gear ensures the distributor rotor aligns accurately, preventing misfires, timing scatter, and accelerated wear on the camshaft or distributor shaft.

  • Material matters: Choose from hardened steel for aggressive cam profiles, bronze for compatibility with billet steel camshafts, or composite gears that reduce gear noise and wear on cast camshafts.
  • Wear protection: Gears with a MELONITE® or similar surface treatment offer increased durability and reduced friction, extending service life under high-rpm operation.
  • Installation note: Always verify gear mesh pattern and end-play during assembly; an incompatible gear material can quickly destroy the camshaft.
  • Whether you are rebuilding a vintage distributor or upgrading to a high-performance ignition system, selecting the correct gear material and tooth profile is essential for reliable engine operation.
