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

The +0.25mm designation means these bearings are 0.25 millimeters larger in diameter than the standard factory size. This is typically used when the crankshaft journals have been machined undersize to clean them up or to account for wear.

What is PMaxBlack and Radialock technology?

PMaxBlack is a special overlay applied to the bearings that allows them to handle higher loads without failing. Radialock is a design feature that helps the bearing achieve the correct crush height when installed, which is crucial for proper oil clearance and seating.

Are these bearings suitable for turbocharged engines?

Yes, this main bearing set is specifically listed as fitting Subaru EJ20, EJ22, and EJ25 engines, including turbocharged variants.
