Collection: Piston Wrist Pins
Piston wrist pins, also known as piston pins or gudgeon pins, play a critical role in connecting the piston to the connecting rod in an engine. These cylindrical pins are inserted through the small end of the connecting rod & the piston's piston bosses. The piston wrist pin allows the piston to pivot & move in a reciprocating motion while maintaining a secure connection to the connecting rod. They are typically made of high-strength steel or other durable materials to withstand the extreme forces & temperatures within the engine. Proper lubrication is essential to reduce friction & wear between the wrist pin & the connecting rod & piston. In some high-performance applications, lightweight & stronger materials like titanium or hardened steel are used to reduce rotating mass & improve engine responsiveness. Upgrading to aftermarket performance wrist pins can enhance engine durability & performance under demanding conditions. Regular inspection & maintenance of the wrist pins are important to ensure their integrity & prevent any potential engine damage.
