What does the King part number Prefix/Suffix mean




NOTE: The term "Undersize" refers to a thicker bearing which is used when the Crankshaft has been turned down and is now undersized, not the bearing itself. The term "Oversize" is typically a thinner bearing than stock to allow for increased clearance.
