Overview of S&S Cycle 4 3/8 in. Stroke Flywheel Assembly w/Sprocket Shaft Bearing Race For 96"/103" /106" Big Bore, 110"/117" w/S&S Pistons - 320-0350

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!

NOTES:

Strokes longer than stock will require S&S Piston Oiler Set, part 31-2026.

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.  If you choose not to convert your crankcases to a Timken sprocket shaft bearing, S&S flywheels may be used in 2003 and later engines by either purchasing the stock compatible flywheels or by installing Harley-Davidson® bearing kit #24004-03B when using S&S flywheels designed for Timken bearings.

This bearing kit adapts the S&S sprocket shaft so it is compatible with stock roller type bearings. Verify that the bearing kit contains the 24604-00D or 24607-07 sprocket shaft bearing. Do not use a 24604-00, 24604-00A, 24604-00B or 24604-00C bearing. Please be advised that if this type of bearing is used, sprocket shaft bearing failure WILL NOT be covered under warranty.

All S&S Flywheels for 2007 and later engines have 7.659” length connecting rods.
