Description
If you’re running a 74″ or 80″ Shovelhead and want more displacement without a complete engine rebuild, the S&S CYCLE 84″ Stroker Flywheel Kit delivers the cubic inches you need. This kit upgrades your engine to 84″ displacement while reusing your stock cylinders—preserving authenticity and eliminating unnecessary expense. With dynamically balanced components and heavy-duty internals, you get measurable power gains and reliability that justifies the investment.
The kit includes everything except pistons: a CNC-machined 4.25″ stroke flywheel assembly, S&S heavy-duty connecting rods, and mainshafts engineered for stroker applications. Installation requires only hand tools for minor crankcase and cylinder modifications, making this a viable upgrade for experienced DIY builders.
