What is a starter ring gear and what does it do?

The starter ring gear is a large gear attached to the flywheel of your engine. When you engage the starter motor, a smaller gear on the starter motor meshes with this ring gear to spin the engine and start it.

Why is the gear heat-treated and black oxide-coated?

Heat-treating makes the metal harder and stronger, which is crucial for withstanding the forces involved in starting the engine. The black oxide coating adds a layer of protection against rust and corrosion.

Does this starter ring gear come with any hardware?

This product is for the starter ring gear only. Any necessary mounting hardware, such as bolts or retaining clips, would typically need to be sourced separately or reused from the original installation if they are in good condition.

This is a well-built replacement part that aims to restore your starter's performance.

The gear itself is black oxide-coated and heat-treated.
