About this product
Upgrade your Harley-Davidson's performance with the S&S Cycle 106" Stroker Flywheel Kit. This kit is designed to increase displacement and boost power, giving your engine a significant performance edge. Built with quality and precision, this flywheel kit delivers reliable performance and durability.
Description
The S&S Cycle 106" Stroker Flywheel Kit features three-piece assembled flywheels with shafts, engineered to enhance your engine's capabilities without requiring motor case modifications. The 4-1/2" stroke significantly increases the engine's displacement to 106", providing noticeable gains in torque and horsepower. For 103" stock motors or those equipped with factory 95" kits, only a piston kit is required for installation. Stock or S&S cylinder heads can be utilized, and stock cylinders will need boring to 3.875". Fuel-injected motors will require recalibration to ensure optimal performance and fuel efficiency. This kit is proudly made in the USA, ensuring top-tier quality and reliability.
