Description
If you’re running a Twin Cam motor at serious power levels, your factory flywheel is a liability. The S&S Cycle 3-piece flywheel assembly eliminates that weak link with forged 4140 steel construction and a larger 1.671″ crankpin that handles aggressive forced induction and high-RPM loads without flex or failure. Built for racers and enthusiasts who demand reliability when it matters most, this is a direct bolt-in upgrade that transforms your engine’s durability and responsiveness.
These are the strongest Twin Cam flywheels available, engineered to pair seamlessly with Timken bearing conversions for maximum longevity. No modifications to your stock crankcase required—just remove, install, and ride with confidence.
