31-0010 65-69 crankcase assembly, STD bore. Natural

Building a classic Pan or Shovel requires a solid foundation, and these S&S Superstock crankcases are much stronger than the original factory units. Sold as a set, they are designed for 1966 to 1969 Early Shovelheads and 1965 Panheads equipped with an aluminum primary housing. These cases come ready for the bench with Timken sprocket shaft races and cam needle bearings already installed. S&S includes cylinder studs, nickel-plated case bolts, and all necessary drain plugs. They are clearanced for up to a 5-inch stroke and use a ported breather design for better oil scavenging. This is a professional-grade solution for both stock restorations and high-performance vintage builds, saving the engine builder substantial labor time during the assembly process.
