What is the primary function of a wrist pin?

A wrist pin, also known as a piston pin, connects the piston to the connecting rod. It acts as a pivot point, allowing the connecting rod to oscillate as the piston moves up and down within the cylinder.

Why is the size of the wrist pin important?

The diameter and length of the wrist pin are critical for proper fitment within the piston and connecting rod. Using the correct size ensures a secure connection and prevents excessive movement or wear.

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.
