What is the purpose of a wrist pin bushing?

A wrist pin bushing fits inside the connecting rod and provides a bearing surface for the wrist pin. This allows the wrist pin to pivot smoothly as the piston moves, ensuring proper alignment and reducing wear.

What is required for installing these bushings?

These bushings typically need to be pressed into the connecting rod and then honed to the correct clearance for the wrist pin. It's recommended to consult Manley's installation instructions or an experienced engine builder for proper procedure.

Are these bushings sold individually or as a set?

The provided information indicates this is a single part number, suggesting it is sold individually. You will need to order the correct quantity for all the connecting rods in your engine.

About this part

Product Details

If you're rebuilding the connecting rods for your BBC (Big Block Chevrolet) engine, getting the right wrist pin bushings is crucial for proper engine operation. These bushings from Manley Performance are designed to fit precisely into the connecting rod, providing a smooth and durable surface for the wrist pin to oscillate within. A well-functioning wrist pin bushing ensures the piston stays securely aligned with the cylinder bore, which is key to preventing piston slap and ensuring consistent power delivery.

Manley is known for making well-built internal engine components, and these bushings are no exception. They are made to handle the stresses and heat generated inside a performance engine. Proper installation is important here; you'll want to ensure these are pressed in correctly and honed to the exact clearance specified by Manley or your engine builder to achieve optimal performance and longevity for your build.
