About This Product
Hastings piston ring set, +.030 inch oversize for a 3-5/16 inch bore. Fits 1937 to 1948 74-inch U-model Flatheads and 1948 to 1952 61-inch E or EL Panheads. The set has 3/32 inch parkerized compression rings and 3/16 inch chromed three-piece oil rings. Hastings uses a low-tension flex-vent design on the oil rings. Verify your piston groove dimensions during the mock-up. That confirms these seat properly in the bore.
Manufacturer part number: 6627030.
