Description for S&S Cycle 3-Piece Flywheel Assembly 

S&S Cycle 3-Piece Flywheel Assembly

• Vast improvement over stock flywheels which shift out of true under heavy load

• Heat-treated 4140 material is 114% stronger than stock, eliminates thrust washer

• Larger 1.671″ crankpin, increased cross-sectional area for increased crank-pin clamping force

• Harder material, no thrust washers required, where stock flywheels have thrust washers

• S&S flywheels have steel gripping the crankpin

• No welding required

• Integral mainshafts,consistent balance and precision machining, truer flywheels and less vibration, and eliminates two potential points of weakness

• 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 which allows more available power

• Includes sprocket bearing race

Note: Strokes longer than stock will require S&S Cycle piston oiler set P/N 424-030. 2007-up stock rod length is 7.659″. Stock pistons in 2007 and later engines require rods with tapered wristpin ends.

Note: Flywheel assemblies supplied with sprocket shaft bearing race installed are compatible with stock roller style sprocket shaft bearings. Assemblies with no race require a Timken sprocket shaft bearing.
