- 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
S&S Cycle model 36-84 BT standard-bore, standard-compression stroker pistons are designed for use in S&S Cycle stroker kits for 1936–1984 Harley-Davidson big-twin applications. These 3-7/16-inch pistons are intended to be used with S&S Cycle stroker flywheels and support displacements based on the selected stroke: 84 cubic inches with a 4-1/2-inch stroke at 8.4:1 compression, 86 cubic inches with a 4-5/8-inch stroke at 9.4:1 compression, or 88 cubic inches with a 4-3/4-inch stroke at 10.8:1 compression.
Modern piston alloys and advanced skirt profiles allow tighter fitting for reduced engine noise and long engine life. The pistons are normally used with stock Harley-Davidson cylinders. Cylinders must be purchased separately according to the required piston oversize. This product is not CARB approved, and carburetor acknowledgement is required.
