What does the .001 inch undersize mean for my engine build?

The .001 inch undersize indicates that these bearings are slightly smaller than standard size. This is typically used when the crankshaft has been ground down by .001 inch to ensure a precise and tight oil clearance between the crank and the main journals.

Are these bearings suitable for a performance engine?

Yes, King Engine Bearings are a popular choice for engine rebuilds and performance applications. Their construction is intended to handle the stresses of a performance V8 engine.

What is the main function of main bearings?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, and they help maintain the correct oil clearance for proper lubrication and engine operation.
