What does the '.020 w/ PC' designation mean for these pistons?

The '.020' indicates that these pistons are .020 inches undersize, meaning they are intended for an engine block that has been bored out to this larger diameter during a rebuild. The 'w/ PC' likely refers to specific skirt coatings or designs intended to reduce friction and noise during operation.

How many pistons are included in this set?

This set includes six pistons, which is the correct number for a 6-cylinder Cummins 5.9L ISB diesel engine.

What is the typical application for an undersize piston set like this?

Undersize piston sets, such as this .020 inch set, are typically used during an engine rebuild or overhaul. They are necessary when the engine's cylinder bores have been machined (honed or bored) to a larger diameter to correct wear, damage, or out-of-round conditions.
