What is the function of a wrist pin bushing?

A wrist pin bushing is located inside the small end of the connecting rod. It provides a smooth, low-friction surface for the piston's wrist pin to pivot within as the piston moves up and down.

Why is this part important for engine rebuilding?

This bushing is crucial for the proper function and durability of your engine's rotating assembly. A worn or improperly fitted bushing can lead to increased wear on the piston, wrist pin, and connecting rod, potentially causing engine damage.

Does this bushing come with a wrist pin?

This product is for the wrist pin bushing only. The wrist pin itself is typically sold separately and must be compatible with the bushing and connecting rod.
