What does the '+1.0' in the part number mean?

The '+1.0' indicates that these bearings are 1.0mm undersize. This means they are intended for use with a crankshaft that has been machined down by 1.0mm, typically to remove wear or damage from the bearing surfaces.

What is the pmax Black racing line?

The pmax Black racing line is King Engine Bearings' performance series. These bearings utilize a tri-metal construction designed for higher load capacity and improved oil pressure control, making them suitable for performance-oriented engine builds.

Are these bearings suitable for a daily driver?

While these are performance bearings, they can be used in daily drivers if the engine is being rebuilt with a focus on enhanced reliability and performance. They are an upgrade over standard bearings and are built to handle more demanding conditions.
