NEW NEW S&S flywhel asemblies You’ve Got To Be Strong…To Go Fast As the performance of an engine is increased, eventually a weak link is found and something fails. One such weak link is the stock flywheel assembly in 1999-to present Harley-Davidson® big twins. If you really put the hammer down, the stock wheels tend to shift out of true. These assemblies are all new, with integral sprocket and pinion shafts, an all new connecting rod and crankpin, and superior materials for added strength. They are a vast improvement over stock, and are even superior to S&S flywheels to date. Fitment • 99-Up Harley-Davidson® big twins – Balanced and unbalanced models • S&S T-Series Engine and Hot Set Up Kit® replacement flywheels Features and Benefits • Heat-treated 4140 material is harder and 114% stronger than stock • New light weight connecting rod forgings • Available with full width wristpin connecting rods • Larger 1.671” diameter crankpin - increased contact area and tighter press fit for a stronger joint. No welding required! • Integral mainshafts - eliminates two potential points of weakness • Consistent balance and precision machining – Truer flywheels and less vibration • Reduced mainshaft deflection at high RPM – less vibration, reduced piston and rod side thrusting, prevents oil pump damage, fully compatible with gear drive cams • Capable of higher rpm – More available power!
