About This Product
These Hastings plus .010 inch oversize piston rings are engineered for 2007 to 2017 96-inch Twin Cam engines. When your 3-3/4 inch bore cylinders require a standard oversize cleanup, these chrome moly rings provide the necessary seal and durability. The set includes 1.5mm compression rings and a 2.5mm oil ring, sold as a pair. They are a direct replacement for OEM 21955-07. In the shop, we trust Hastings for their consistent quality and their low-tension oil ring technology, which helps maintain power by reducing internal drag. Always verify your piston groove dimensions to ensure a perfect match for these precision rings.
Manufacturer part number: 2M4805010.
