Description
Description for 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
- Does not include sprocket bearing race
Note: Strokes longer than stock will require S&S Cycle piston oiler set (MPN# 31-2026). 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.
