S&S CYCLE Flywheel - Stroker - Twin Cam 320-0358

If you're pushing your Twin Cam engine toward higher displacement and increased power output, the stock flywheel becomes your limiting factor. The S&S CYCLE Stroker Flywheel is engineered to handle the demands of forced induction and aggressive tuning without risking catastrophic crankshaft failure. Built from 4140 steel with a larger 1.671" crankpin, this 3-piece design delivers the strength and durability serious builders demand.

The integral main shaft design eliminates weak points, while the Timken bearing conversion compatibility gives you options for long-term reliability. Installation is straightforward—these flywheels fit directly into stock crankcases with zero modifications required. You get American manufacturing quality and proven performance, all without tearing down your engine cases.
