These 3-7/16" +.050" 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

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.
