S&S Forged 3 5/8" Bore Piston For 1936-'84 OHV Big Twins - +.010"

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" (43/4" 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).

NOTES:
Compression ratios will change when replacing existing pistons in S&S engines with this series of forged pistons. If higher compression is desired, we suggest shortening cylinders, or decking heads to achieve the desired compression ratio. A change of .060" will produce approximately 1 point of change in the compression ratio. S&S offers machine shop services through the S&S Service and Speed Center. New pistons can be fit to your existing cylinders for a reasonable charge, and cylinders can be shortened to your specifications if higher compression ratio is desired.
