50-8329-2 Crankpin end plug set. For 1.500" crankpin

These S&S crankpin end plugs are essential for properly setting up the bottom end on older S&S T-series engines. Sold as a pair, these plugs are designed for use with 1.500-inch diameter press-in crankpins found in S&S flywheels manufactured in 2012 and earlier. Their primary job is to expand the crankpin within the flywheels to ensure a rock-solid, interference fit that can handle the stresses of a high-performance V-twin. These are specific to the 1.500-inch pins and should not be confused with the larger plugs used for later 1.671-inch pins. If you are rebuilding a 1999 to 2012 S&S T-series motor, these are the correct components to ensure your crank assembly stays true and secure.
