PISTON RING SET 4 CYL STD (Doosan DWKM4942154)

A worn piston ring set can allow combustion gases to bypass the piston, reducing compression and causing power loss. This aftermarket replacement part references the Doosan catalog number DWKM4942154. The set includes rings for a four-cylinder standard-bore application. Piston rings seal the gap between the piston and cylinder wall during operation. A common failure consequence is increased oil consumption as rings lose their sealing ability. The part is a retaining ring type, which holds the piston assembly together under dynamic loads. Verify the serial number or application, then call (562) 693-7748.
