What is the function of a wrist pin bushing?

A wrist pin bushing, also known as a piston pin bushing, is located in the small end of the connecting rod. Its main job is to provide a smooth, low-friction surface for the piston wrist pin to pivot within as the piston moves up and down.

Why is using a quality wrist pin bushing important?

Using a well-made wrist pin bushing is important for engine longevity. A worn or improperly fitted bushing can lead to excessive play, noise, and premature wear on both the connecting rod and the piston pin, potentially causing more significant engine damage.

Does this bushing come with a piston pin or connecting rod?

This product is for the wrist pin bushing only. It is sold individually and does not include the piston pin or the connecting rod itself.
