What is the main purpose of main bearings?

Main bearings support the crankshaft within the engine block. They create a low-friction surface for the crankshaft to rotate on, ensuring proper alignment and reducing wear on critical components.

Are these bearings suitable for a stock engine rebuild?

Yes, these are standard size high-performance main bearings. While they offer improved strength and wear resistance for performance applications, they are also a well-built replacement for stock engines needing a refresh.

What does 'standard size' mean for these bearings?

Standard size means the bearings are manufactured to the original equipment manufacturer's (OEM) specifications for diameter. They are intended to be used when the crankshaft journals are still within their original factory dimensions, without excessive wear.
