What is the purpose of a wrist pin?

A wrist pin, also known as a piston pin, connects the piston to the connecting rod. It allows the piston to pivot while the connecting rod moves in its circular path, transferring power from combustion.

What does the wall thickness specification mean?

The 0.250-inch wall thickness refers to the thickness of the material forming the hollow center of the wrist pin. A thicker wall generally contributes to increased strength and durability under load.

Why is this part not CARB approved?
