Flywheel Assembly - 4.625" Stroke - Carbureted Models - Evolution Big Twin '84-'98

The S&S CYCLE Flywheel Assembly for Evolution Big Twin engines is engineered for high-performance applications and stock replacements. Crafted from high-strength forged steel, this assembly offers durability and reliability for demanding riding conditions. The 8-1/2-inch diameter flywheel features a large diameter tapered sprocket shaft with a 6° keying angle, providing increased contact area and enhanced strength to withstand high torque loads. This design ensures improved power transmission and longevity during high-performance use. Equipped with a standard S&S tapered crankpin and pinion shaft, the assembly is designed for ease of service, facilitating maintenance and repairs. The kit includes a flywheel, crankpin, and connecting rods, all fully assembled, trued, and balanced to match stock Harley-Davidson 80-inch or 96-inch pistons, ensuring smooth operation and precise fitment. Manufactured in the USA, this flywheel assembly is suitable for carbureted Evolution Big Twin models from 1984 to 1998. Please note that models from 1990 to 1999 will require a pinion shaft conversion kit for proper installation. Whether upgrading a stock engine or building a high-performance custom setup, this assembly provides a reliable foundation for your Harley-Davidson project.
