What does the '+.002mm' housing bore specification mean?

This specification means the bearings are designed to fit into an engine block housing bore that is 0.002 millimeters larger than the standard factory bore size. This is often done during engine rebuilding to achieve precise oil clearances.

What is the 'pmax black racing line' and what are its benefits?

The pmax black racing line signifies that these bearings utilize a high-performance tri-metal construction. This material offers improved load-carrying capacity and wear resistance, making them suitable for engines that experience higher stresses.

Do these bearings come with installation hardware?

This product is a set of main bearings only. Installation hardware, such as main cap bolts or seals, are typically sold separately and should be sourced according to your vehicle's service manual.
