Product Introduction

A piston pin is a cylindrical metal rod that connects the piston to the connecting rod in an internal combustion engine. It allows for the reciprocating motion of the piston while keeping it from rotating. The piston pin must be strong enough to withstand high pressures and temperatures generated by the engine, while also being lightweight to minimize engine weight and reduce friction. Part number 3934046 is a specific type of piston pin that is designed for use in certain models of trucks or other vehicles.
