S&S Cycle 36-84 BT 3-7/16in x Up To 4-3/4in Stroke HC Piston Set - Standard

These 3-7/16" standard bore, standard compression stroker pistons are part of an S&S stock bore stroker kit for 1936-'84 HD® big twins, and are designed to be used in conjunction with S&S® stroker flywheels. Flywheels of the following strokes may be used for the following displacements: 4-1/2" stroke - 84" @ 8.4:1 compression, 4-5/8" stroke - 86" @ 9.4:1 compression, 4-3/4" stroke - 88" @10.8:1 compression.

The modern alloys used in these pistons, coupled with the advanced skirt profiles, allow them to be fit tighter resulting in low engine noise and long engine life

These pistons are normally used in stock HD® cylinders, and must be purchased separately, based on the required piston oversize
