These forged 3 5/8″ bore stroker piston replaces several cast and forged big bore pistons that S&Spreviously 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&Swill fit these pistons to your existing cylinders (when purchasing new cylinders, pistons can be fit to them as an option).
- Forged pistons for superior strength
- Modern alloys and piston skirt profiles for low noise and long engine life
- Includes set of pistons, rings, wristpins, and clips
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.
