S&S Cycle 2007+ BT 4-5/8in Stroke Flywheel Assembly w/o Sprocket Shaft Bearing Race

This 4-5/8" stroke 8-1/2" diameter flywheel assembly replaces the original flywheels in S&S® T124 T2 engines, and fits 2006 HD® Dyna models and all 2007-'16 big twin models as part of an S&S® 124" Hot Set Up Kit®. Sprocket shaft does not have a stock style bearing race pressed on. This three piece design flywheel assembly is for crankcases with Timken® sprocket shaft bearing. Assembly is trued to less than .0005" runout on pinion and sprocket shaft bearing surfaces, making them capable of higher rpm and fully compatible with gear drive cams.

• Flywheels are CNC machined from heat-treated, closed die, steel forgings, which are 114 percent stronger than late style stock steel flywheels
• Fully assembled with premium quaility S&S® heavy duty 7.667" connecting rods, with full width wrist pin ends, and dynamically balanced
• The only joints in the assembly are where the 1.671" diameter connecting rod crankpin is pressed into the flywheels
• Pinion and sprocket shafts are forged as part of the flywheel

The S&S Cycle Part Number SSC320-0464 is a high-performance flywheel assembly designed specifically for Harley Davidson big twin engines from 2007 onward, including 2008 and 2009 models such as the Road King, Road King Classic, Electra Glide Standard, and Street Glide. This assembly features a 4-5/8 inch stroke and an 8-1/2 inch diameter, providing increased torque and power output for enhanced riding experience. Crafted from heat-treated steel forgings, these CNC-machined flywheels are 114% stronger than traditional stock units, ensuring durability and reliable performance under demanding conditions. The assembly is fully balanced and pre-assembled with premium heavy-duty 7.667-inch connecting rods, with full-width wrist pin ends, minimizing vibrations and promoting smooth operation. The design includes a precision-trued pinion and sprocket shaft with less than .0005 inch runout, making them suitable for higher RPM applications and compatible with gear drive cams. Unlike stock flywheels, the sprocket shaft does not feature a stock-style bearing race pressed on, and the assembly is intended for crankcases with a Timken sprocket shaft bearing, ensuring a secure fit. The only joints are where the 1.671-inch diameter connecting rod crankpin is pressed into the flywheels, maintaining structural integrity and ease of assembly. This powertrain component is ideal for riders seeking increased engine performance and longevity in their Harley Davidson big twin motorcycles. Please note that this part is not CARB approved and is intended for off-road or racing applications only. Proper installation and compatibility should be confirmed prior to use to ensure optimal performance and safety.
