What is the purpose of a piston wrist pin?

A piston wrist pin, also known as a gudgeon pin, connects the piston to the connecting rod. It allows the piston to pivot relative to the connecting rod as the crankshaft rotates, enabling the piston to move up and down within the cylinder.

Why is the wall thickness of a wrist pin important?

The wall thickness contributes to the overall strength and rigidity of the wrist pin. A thicker wall generally means a stronger pin, which is important for handling the significant forces generated during engine operation, especially in high-performance applications.

What does 'Not CARB approved' mean for this part?

This means the part does not meet the emissions standards set by the California Air Resources Board (CARB). Consequently, it cannot be legally sold or shipped to California due to these regulations.
