What is the purpose of an external retaining ring in an engine?

An external retaining ring is used to secure a component, like a piston pin (wrist pin), within a groove. It prevents the pin from moving out of place, ensuring the piston and connecting rod assembly functions correctly.

Why does this pack include 10 retaining rings?

This pack includes ten rings to provide spares for your project. It's common to have extra rings on hand in case one is dropped, bent, or if you are working on multiple engines or cylinders.

Are these rings suitable for all engine builds?

These rings have specific dimensions (.382in x .021in) and are intended for applications where those measurements are required for piston pin retention. Always verify the correct size needed for your specific engine build.
