What is the purpose of a piston wrist pin?

The wrist pin, also known as a piston pin, is a crucial component that connects the piston to the connecting rod. This connection allows the piston to pivot as it moves up and down within the cylinder, transferring power to the crankshaft.

What does 'unchromed' mean for this piston pin?

An unchromed piston pin means the surface has not been plated with chromium. This can be beneficial for certain engine builds where specific surface treatments or clearances are required, or if you plan to apply a different coating.

Why is this part not CARB approved?

This piston pin is not CARB (California Air Resources Board) approved, which means it cannot be legally shipped to California. This is often due to emissions regulations or specific material certifications required in that state.
