About This Product
Hastings chrome-moly piston rings for late 1978 to 1984 Shovelhead 1340cc Big Twins. This set fits a 3-1/2 inch bore with .005 inch oversize. You get 1.6mm top and second compression rings and a 4.75mm three-piece flex-vent oil ring. Hastings keeps the oil ring tension low to reduce drag while still controlling the oil. Measure your piston groove heights before installation to confirm the rings seat properly. Sold as a pair.
Manufacturer part number: 2M6127005.
