About This Product
These Hastings piston rings are a premium choice for 2017 to 2024 107-inch Milwaukee-Eight engines requiring a +.005 inch oversize. Designed for a standard cylinder bore of 3.937 inches, these rings provide a precise fit for slightly worn or honed cylinders. The set includes a chrome top compression ring, a ductile iron Napier second ring, and a three-piece chrome flex-vent oil ring for superior lubrication control. Sold as a pair, these rings are engineered to meet or exceed OEM standards, ensuring your M8 maintains optimal compression and oil management. Always verify your piston groove heights, which should be 1.2mm for the compression rings and 2.0mm for the oil ring, before beginning your engine build.
Manufacturer part number: 2C5231005.
