What does the +0.25mm size mean for these bearings?

The +0.25mm sizing indicates that these bearings are designed for crankshaft journals that have been machined down by 0.25mm (approximately 0.010 inches). This is typically done to clean up minor imperfections or wear on the crankshaft surface.

What type of engine is this bearing set best suited for?

These bearings are ideal for medium-load engines. Their lead-free composite and bi-metal aluminum construction are designed to handle the demands of such applications effectively.

Does this bearing set come with installation hardware?

This product listing is for the main bearing set only. Installation hardware, such as main cap bolts or seals, is typically sold separately and should be checked against your vehicle's specific repair manual.
