What is the main purpose of main bearings?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the immense forces generated during combustion. Proper main bearings are essential for engine longevity and performance.

What does 'STD' size mean for these bearings?

STD refers to 'standard' size. This means the bearings are manufactured to the original equipment manufacturer's specifications for a new crankshaft. If your crankshaft has been machined or is undersized, you would need a different size bearing.

What is PMaxBlack technology?

PMaxBlack is King Engine Bearings' proprietary technology designed to enhance the load-carrying capacity of their bearings. This is particularly beneficial for performance applications or engines that experience higher stresses.
