PISTON RING SET 4 CYL 1.00 (Doosan DWKM4942156)

A worn piston ring set can allow combustion gases to escape past the piston, reducing compression and power output. This aftermarket replacement part references the OE maker Doosan and carries the cross-reference part number DWKM4942156. The set includes multiple rings that seal the gap between the piston and cylinder wall during operation. A common failure consequence is increased oil consumption as the rings lose their ability to control oil film on the cylinder surface. In a four-cylinder configuration, this set provides rings for all pistons in the assembly. The part is listed as a piston ring set for a 4-cylinder application with a 1.00 oversize specification. Verify the serial number or application, then call (562) 693-7748.
