Product Details

Flathead Forged Piston Set (106-5536) by S&S Cycle®. Flathead Power® Forged 3-5/8" bore stroker pistons replace 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.

Notes

Compression ratios will change when replacing existing pistons in S&S engines with this series of forged pistons. If higher compression is desired, they suggest shortening cylinders, or decking heads to achieve the desired compression ratio. A change of 0.060" 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.
