S&S Cycle 36-84 BT Forged 3 5/8in Bore Piston - .030in

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.

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.
