What is the primary function of a wrist pin bushing?

A wrist pin bushing sits between the connecting rod and the piston's wrist pin. Its main job is to allow for smooth movement and prevent wear on both the rod and the pin as the piston reciprocates.

What material is this bushing made from and why is it important?

This bushing is made from a bronze alloy. Bronze is chosen for its excellent wear resistance and low friction properties, which are essential for surviving the high-stress conditions within an engine's rotating assembly.

Does this bushing come with installation hardware?

This product listing is for the wrist pin bushing only. Installation hardware, such as retaining clips or the wrist pin itself, is typically sold separately and may require specific tools for proper installation.
