What does the 'P30' mean in the part number?

The 'P30' designation indicates that these main bearings are 0.030 inches undersize. This means they are intended for use with a crankshaft that has been machined down by 0.030 inches to account for wear or to achieve a specific clearance.

What is the primary function of main bearings?

Main bearings are essential components in an engine's bottom end. They support the crankshaft within the engine block, allowing it to rotate smoothly while handling significant loads and minimizing friction.

Are these bearings suitable for a performance engine build?

Clevite is known for durable engine components, and this main bearing set is built for performance and longevity. However, always ensure your engine's specific requirements and clearances are met for any build, especially performance applications.
