Features
The S&S Flywheel builds a strong, reliable bottom end for stock or high-performance engines. It is made from forged steel.
Fits Harley-Davidson Touring (1970-1984), FXR (1982-1983), FX Big Twin (1971-1984) and Vintage (1970-1980) models. Check the fitment chart below to confirm your exact year and model.
- Flywheels are CNC machined from heat-treated, closed die, steel forgings, and are stronger than cast iron or late style steel flywheels
- Replaces the original flywheels in S&S® 80" SH80 engines with alternator style crankcases for '70-'84 Big Twin
- Can be used to overhaul an S&S engine or to build a custom engine using similar crankcases and pistons
- Features 4-1/4" stroke, 8-1/2" diameter flywheels, and 7.440" connecting rods
- May also be used in 88" engines with 3-5/8" bore cylinders
- Made in the USA
