These forged 3 5/8" bore stroker piston replaces several cast and forged big bore pistons that S&S® previously offered. Applications for this piston include 88" (4 1/4" stroke), 93" (4 1/2" stroke), and 96" (4 5/8" stroke) engines with stock 8 1/2" diameter flywheels, and 98" (4 3/4" stroke) and 103" (5" stroke) engines with 8 1/4" small diameter flywheels. As with the new stock bore stroker piston, the modern metallurgy and advanced skirt profiles allow a relatively close piston fit for low engine noise and long engine life. S&S® will fit these pistons to your existing cylinders (when purchasing new cylinders, pistons can be fit to them as an option.
