About This Product
These Hastings piston rings are a premium choice for late-style Flathead rebuilds. This .050 inch oversize set is designed for 1950 to 1973 45-cubic inch (750cc) Flatheads, as well as 1952 to 1956 K-model 45s and KH or KHK 55-cubic inch (900cc) models. The set features 1.6mm gray iron parkerized compression rings and a 4.75mm three-piece flex-vent style chrome oil ring. Note that these are specifically for the later style pistons and will not fit the 1929 to 1949 early type pistons which used thicker rings. With a standard bore of 2.745 inches, these rings provide excellent sealing and oil control. Always measure your piston grooves before installation to ensure these high-quality Hastings rings are the correct match for your specific engine build.
