What does the 0.25 size mean for these bearings?

The 0.25 size indicates that these bearings are 0.025 inches undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.025 inches to correct for wear or damage.

What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while handling the significant forces generated during combustion, and they maintain the critical oil clearance between the crankshaft and the block.

Are these bearings suitable for a stock Duramax engine?

These bearings are specifically sized 0.25 inches undersize, meaning they are for a crankshaft that has already been machined down. They are not for a stock, unmachined crankshaft. Always ensure your crankshaft has been properly measured and machined to the correct undersize before installing these bearings.
