What is the pMaxBlack coating for?

The pMaxBlack coating is applied to the bearing surface to help protect it during the engine's break-in period. It's designed to reduce friction and wear when the engine is first started and oil pressure is still building.

What does the .001 size mean for these bearings?

The .001 size indicates that these bearings are slightly larger than standard main bearings. This is typically used when the crankshaft journals have been machined down slightly, and you need a bearing to match that new size for proper clearance.

Are these bearings sold individually or as a set?

This product is a set of main bearings. It includes all the main bearings needed for a complete engine build for the specified V6 applications.

About this part

Product Details

In this set, you get the main bearings for your Buick, Pontiac, or Oldsmobile V6 engine, specifically sized at .001 inch larger than standard. These bearings feature King's pMaxBlack coating, which is designed to help protect the bearing surface during the critical break-in period. This coating is a solid layer that helps to reduce friction and wear when the engine is first started and oil pressure is building.

King Engine Bearings are a popular choice for engine rebuilds. The pMaxBlack coating is a notable feature that adds an extra layer of protection, especially important for performance builds or engines that might see harder use. This coating is applied to the bearing surface to help prevent damage during the initial hours of operation, which is often the most vulnerable time for new bearings.
