On vehicles with mechanical spark timing, the distributor gear sits at the bottom of the distributor’s shaft, where it meshes with the gear on the camshaft. This gear can wear out over time, or you might need one that’s compatible with a new camshaft. To maintain proper timing, grab your new distributor gear right here at Summit Racing Equipment!

On vehicles with mechanical spark timing, the distributor gear sits at the bottom of the distributor’s shaft, where it meshes with the gear on the camshaft.

Gear Materials
If the distributor gear is softer than the cam, it’ll wear out quickly. If it’s harder than the cam, the cam gear will wear out (which is a more expensive repair). Ideally, the distributor gear should be slightly softer.
Distributor gears are available in four different materials: composite (light, durable, and soft), bronze (for use with billet steel cams), cast iron (for use with cast iron, flat tappet cams), and melonized or hardened steel (the hardest material, used for OEM replacements). For a more complete explanation of the materials and their compatibility, check out our Help Center article.
