What is the 'pMax Black' racing line?

The pMax Black racing line refers to King Engine Bearings' high-performance series. These bearings utilize a tri-metal material designed for enhanced durability and load-carrying capacity, making them suitable for rebuilt or performance-oriented engines.

What does the '.026' size mean for these bearings?

The '.026' indicates that these main bearings are .026 inches undersize. This sizing is typically used when the crankshaft journals have been machined down during an engine rebuild to ensure proper clearance and oil film.

Are these bearings sold individually or as a set?

This is a complete set of five crankshaft main bearings, which is what you need to replace all the main bearings on your compatible Ford 2.3L engine.
