What does the 0.05mm size designation mean for these bearings?

The 0.05mm size, also noted as +.003 inches, indicates these bearings are slightly larger than standard. This is intentional and means they are designed to be used when the engine's crankshaft journals have been machined undersize to correct wear.

What is the 'Smart Choice' material?

The 'Smart Choice' material is a unique overlay developed by King Engine Bearings. It's designed to offer better durability and lower friction, contributing to the overall performance and lifespan of the engine.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. Typically, a set includes enough bearings for all the connecting rods in the specified engine.
