RING SET - PISTON (1) (Mitsubishi MB328158)

MB328158: A worn retaining ring can allow a piston to shift, leading to loss of compression or mechanical noise. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB328158. The retaining ring secures the piston within its bore by snapping into a groove, preventing axial movement during operation. A failed ring may cause the piston to contact the cylinder wall, resulting in scoring or seizure. Keeping a retaining ring in sound condition helps maintain proper piston alignment and consistent clearance. The item ships at approximately 0.254 pounds. Verify the serial number or application, then call (562) 693-7748.
