What is the purpose of a piston pin?

A piston pin, also known as a wrist pin, connects the piston to the connecting rod. It allows the piston to pivot while the connecting rod moves in its circular path, ensuring the piston assembly stays securely aligned.

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 reduces friction and wear where the pin contacts the piston and connecting rod, contributing to better performance and longevity.

Why is this piston pin not chromed?

This piston pin features a non-chromed finish, often chosen for specific engine builds where a particular material property or surface treatment is preferred over chrome plating. It is designed for secure fitment and smooth operation within the piston and connecting rod.
