S&S Cycle 106-5535

This new forged, high compression, 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 81/2" 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. 3-5/8" bore, standard bore.
