What does the 0.25 sizing mean for these main bearings?

The 0.25 sizing indicates that these bearings are 0.025 inches (or 0.635mm) undersize compared to standard main bearings. This is used during engine rebuilding when the crankshaft journals have been machined undersize to correct wear or damage.

What is the benefit of the PMaxBlack coating and Radialock technology?

PMaxBlack coating is designed to handle superior load capacity, which is important for performance engines. Radialock technology helps to ensure the bearings have the optimal crush height, which is crucial for them to seat properly in the engine block and main caps.

Does this main bearing set come with everything needed for installation?

This product is a set of main bearings. It does not typically include crankshafts, seals, gaskets, or other related engine components. You will need to ensure you have all necessary parts and fluids for a complete engine rebuild.
