What is the purpose of a piston pin?

The piston pin, also known as a wrist pin, connects the piston to the connecting rod. It allows the piston to pivot as the connecting rod moves, transferring the combustion force to the crankshaft.

What does 'superfinished outer diameter' mean for this piston pin?

A superfinished outer diameter means the surface of the pin has been treated to be exceptionally smooth. This helps reduce friction and wear where the pin contacts the piston and connecting rod, promoting longer component life.

Does this piston pin come with clips or retainers?

The manufacturer description mentions Wiseco piston clips and wrist pin retainer sets are available separately to maximize security. This specific part number is for the piston pin itself.
