What does the '+.025' sizing mean for these bearings?

The '+.025' indicates that these main bearings are 0.025 inches undersize. This means they are intended for use when the engine's crankshaft journals have been machined down by 0.025 inches during a rebuild to ensure proper oil clearance.

What is the 'pmax black' coating on these bearings?

The pmax black coating is part of King's XP racing line. This coating is applied to help reduce friction and improve the durability of the bearings, especially in high-performance engine applications.

Are these bearings suitable for a stock SR20DET engine?

These are performance bearings from King's XP racing line, featuring a special coating. While they can be used in a stock engine, they are specifically designed to handle increased stress and demands often found in modified or performance-oriented SR20DET builds.
