What does '0.25mm Undersize' mean for these bearings?

This means the bearings are made to fit crankshaft journals that have been machined down by 0.25mm. It's crucial to match the bearing size to the journal size for correct oil clearance and engine health.

Do these bearings come with new main bolts?

This set includes the main bearings only. New main bearing bolts are typically recommended for engine rebuilds, but they are sold separately.

What is the typical oil clearance when using these bearings?

ACL bearings are designed to provide optimal oil clearance within the manufacturer's specifications when used with a properly machined crankshaft. Always consult the service manual for your specific engine for exact clearance ranges.
