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 as the connecting rod moves, converting the linear motion of the piston into the rotational motion of the crankshaft.

What does the size '21mm X 2.250' refer to?

The '21mm' refers to the outer diameter of the wrist pin, and '2.250' refers to its length in inches. These dimensions are critical for ensuring a proper fit with your pistons and connecting rods.

Can this product be shipped to California?
