What is the purpose of a wrist pin bushing?

A wrist pin bushing sits inside the small end of the connecting rod. It provides a smooth, durable surface for the piston's wrist pin to rotate within, reducing friction and wear.

Why is proper fitment of the wrist pin and bushing important?

Correct clearance between the wrist pin and the bushing is essential for engine longevity. Too much play can lead to excessive noise and premature wear, while too little can cause binding and damage.

Are these bushings sold individually or as a set?

The part number 42305-8 refers to a single wrist pin bushing. You will need to order the quantity required for your specific engine build.
