What is the purpose of a piston wrist pin?

The piston wrist pin, also known as a gudgeon pin, is a crucial component that connects the piston to the connecting rod. It allows the piston to pivot relative to the connecting rod as the crankshaft turns, enabling the transfer of power from combustion to the drivetrain.

Why is this wrist pin unchromed?

This wrist pin features an unchromed finish. This is often specified for performance builds where precise tolerances and minimal friction are key. The unchromed surface can contribute to efficient operation and reduced wear within the piston and connecting rod assembly.
