What does '0.50 Oversized' mean for these bearings?

This means the bearings are 0.50mm larger in diameter than standard. They are designed to be used when the engine's crankshaft has been machined down by 0.50mm to ensure a proper fit and clearance during an engine rebuild.

What is the material of these main bearings?

These bearings are made from a bimetal material with an aluminum silicon base. This type of construction is chosen for its good heat dissipation and wear resistance characteristics in engine applications.

Do these bearings come with installation hardware?

This listing is for the main bearing set only. Installation hardware, such as main cap bolts, is typically sold separately and should be replaced with new, high-strength hardware during an engine rebuild.
