■Product Description 3-7/16" +0.030" bore standard compression stroker pistons are a component of S&S genuine bore stroker kits for 1936-84 HD Big Twins, designed for use with S&S stroker flywheels. Flywheels with the following displacements can be used: 4-1/2" stroke 84Ci with 8.4:1 compression ratio, 4-5/8" stroke 86Ci with 9.4:1 compression ratio, 4-3/4" stroke 88Ci with 10.8:1 compression ratio. These pistons are typically used with stock cylinders and must be purchased separately depending on the required piston oversize.
