S&S CYCLE 4-1/4" Stroke Flywheel Assembly For S&S® V80 and '84-'99 HD® Evolution® Carbureted Big Twin Engines - 32-2239
This 4-1/4" stroke 8-1/2" diameter flywheel assembly replaces the original flywheels in S&S® 80" V80 engines and in 1984-'99 HD® Evolution big twins. Balanced to stock 80" cast pistons. Flywheels are CNC machined from heat-treated, closed die, steel forgings, and are stronger than cast iron or late style steel flywheels. Dynamically balanced and fully assembled with premium quaility S&S® mainshafts and heavy duty 7.440" connecting rods.
- Made of high-strength forged steel and designed for stock and high-performance custom applications
- Special keyed 6 large diameter tapered sprocket shaft that provides more contact area for increased strength
- Standard S&S tapered crankpin and pinion shaft are used for ease-of-service
- 8-1/2" diameter with 4-1/4" or 4-5/8" stroke
- Kits come fully assembled, trued and balanced to stock H-D 80" or 96" pistons
- Include flywheel, crankpin and connecting rods
- Made in the U.S.A.
NOTE: This part requires additional parts in order to function properly. Please add all additional required parts to your order as needed.
NOTE: IMPORTANT: 1977–’89 style pinion gears, spacers, and nuts are required when installing S&S flywheel assemblies. For installation in 1990–’99 or scratch built engines, order S&S Pinion Shaft Conversion Kit 33-4148. S&S flywheels are no longer available machined for stock Harley-Davidson® main shafts. 4¼" stroke assembly is balanced for stock HD® 80" pistons. 45/8" stroke assembly is balanced for S&S stock bore and 35/8" bore stroker pistons. Use special order Part # for flywheels balanced to other pistons or rods. All S&S crankcases for 1984–’99 big twin engines are machined to accept a crank position sensor and can be used with these flywheels.
