What is the main function of a wrist pin?

A wrist pin, also known as a piston pin, is a hollow metal tube that connects the piston to the connecting rod. It allows the connecting rod to pivot as the piston moves up and down in the cylinder.

Are these wrist pins compatible with all SBC engines?

These wrist pins are designed for Small Block Chevy (SBC) engines and have specific dimensions (.927in diameter, 2.300in length, .150in wall thickness). It's important to verify these dimensions match your specific pistons and connecting rods.

What does 'Not CARB approved' mean?

This means the part does not meet the emissions standards set by the California Air Resources Board (CARB). As a result, it cannot be legally shipped to or installed on vehicles registered in California.
