MSD Bronze Distributor Gear 0.530" ID for Ford 351W 8585

The distributor gear is a high-wear component that directly impacts ignition timing accuracy and engine reliability. Stock gears wear quickly under sustained RPM, causing timing drift and performance loss. The MSD Bronze Distributor Gear replaces that weakness with premium materials and hardening treatments designed to maintain precise timing for thousands of miles.

Built from AMPCO 45 aluminum bronze with 5% nickel content, this gear delivers the strength needed for aggressive cam profiles and high-RPM applications while resisting the wear that compromises stock components. The Melonite QPQ coating and micro-polished surface reduce friction during initial startup and throughout the gear's service life, preserving distributor accuracy when it matters most.

Direct fit for Small Block Ford 351 Windsor engines. Bolt-on installation—no modifications required.
