What is the main purpose of main bearings?

Main bearings sit between the crankshaft and the engine block. Their primary job is to support the crankshaft, allowing it to rotate smoothly while handling the immense forces generated during combustion.

What does 'Standard X' size mean for these bearings?

Standard size means these bearings are meant to be installed on a crankshaft that has not been machined or ground undersize. If your crankshaft journals are within factory specifications, this standard size bearing set will fit correctly.

What is the Alecular racing line?

The Alecular racing line from King Engine Bearings uses a bi-metal construction with a special aluminum alloy. This design offers improved strength and wear resistance, making them suitable for high-performance applications where standard bearings might not hold up.
