What does the +0.5 size mean for these bearings?

The +0.5 designation indicates that these bearings are 0.5mm larger than standard size. This means they are intended for use when the crankshaft journals have been machined down by 0.5mm to account for wear or to achieve a specific clearance.

What is PMaxBlack and Radialock?

PMaxBlack is King's overlay material that offers superior load capacity for demanding applications. Radialock is a feature that helps achieve optimal crush height, ensuring the bearing seats properly in the block or main caps.

Do these bearings come with installation instructions?

While this set is designed for a direct fit, it is always recommended to refer to the manufacturer's installation instructions or a qualified mechanic for proper torque specifications and assembly procedures.
