S&S Cycle 320-0469 Flywheel Assembly Stroke Engine Crankshaft - 3-Piece 4-5/8

The S&S Cycle 3-Piece Flywheel Assembly with 4-5/8" stroke delivers exceptional strength and reliability for high-performance V-twin applications. Engineered to replace stock flywheels that can shift out of true under heavy loads, this precision-machined assembly provides the durability needed for demanding riding conditions.

Key Features:

• Heat-treated 4140 steel construction is 114% stronger than stock flywheels
• Integral mainshafts ensure truer flywheel operation and reduced vibration
• Larger 1.671" crankpin with increased cross-sectional area for superior clamping force
• Eliminates thrust washer for simplified installation and improved reliability
• No welding required for assembly
• Does not include sprocket bearing race

Important Installation Notes:

• Strokes longer than stock require S&S piston oiler set #31-2026
• 2007 and later stock rod length is 7.659 inches
• Stock pistons in 2007+ engines require connecting rods with tapered wristpin ends

This flywheel assembly is designed for S&S 124 cubic inch engine builds and is compatible with various Harley-Davidson Softail models from 2001-2006. The superior material strength and precision engineering make this an essential component for builders seeking maximum performance and longevity from their V-twin engines.
