Description

A piston ring set is a collection of circular metal rings that fit around the piston of an internal combustion engine. It includes two compression rings and one oil control ring. The compression rings create a seal between the piston and cylinder wall to prevent gas leakage during combustion, while the oil control ring scrapes excess oil off the cylinder wall to prevent it from entering the combustion chamber. The part number refers to a specific type of piston ring set designed for use in certain truck engines. It is important to choose the correct size and type of piston ring set for your engine to ensure proper functioning and longevity.
