What is the purpose of a wrist pin bushing?

A wrist pin bushing sits between the connecting rod and the piston's wrist pin. Its job is to create a smooth, low-friction surface for the wrist pin to rotate within, ensuring proper alignment and preventing wear on both components.

What does the sizing (OD/ID/OAL) refer to?

OD stands for Outer Diameter, which is the measurement across the outside of the bushing. ID stands for Inner Diameter, the measurement across the inside where the wrist pin fits. OAL is the Overall Length of the bushing.

Does this bushing come with installation instructions?

Refer to the manufacturer's installation instructions for details on proper installation procedures. Proper fitment and installation are crucial for engine longevity.
