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 1.671in. crankpin, increased cross-sectional area for increased crank-pin clamping force. No welding required. Integral mainshafts, truer flywheels and less vibration. Notes: Strokes longer than stock will require S&S piston oiler set #31-2026. 07-up stock rod length is 7.659in.. Stock pistons in 2007 and later engines require rods with tapered wristpin ends.
