33-2003 Sprocket shaft assembly

For the late Panhead and early Shovelhead era, this S&S tapered sprocket shaft assembly is the go-to choice for a robust bottom end. It is designed to fit 1965 to 1969 Big Twin models and must be used in combination with S&S SE and SL flywheels. The tapered design is a hallmark of this era's engine architecture, and S&S has refined the manufacturing process to ensure superior strength and precision over original equipment. This assembly is built to withstand the increased demands of performance riding while maintaining the smooth operation of your crankshaft. Sold as an assembly, it is a vital part of any high-quality engine overhaul for these classic 1960s machines.
