S&S Cycle Flywheel Assembly - 320-0603

Upgrade your engine's performance with the S&S Cycle Flywheel Assembly. Designed for gear drive camshafts, this assembly offers superior strength and precision. Experience smoother operation and enhanced reliability with this high-quality, American-made component.

Description

The S&S Cycle Flywheel Assembly is engineered for demanding applications, providing a robust foundation for your high-performance engine build. Precision machining and consistent balance ensure smooth operation, while the heat-treated 4140 steel construction delivers exceptional strength – twice as strong as stock components. The connecting rods are designed using Finite Element Analysis (FEA) to eliminate weak spots, ensuring maximum durability. The balance gear is pre-installed for easy installation, eliminating the need to weld the crankpin. Ideal for 114" and 117" displacement engines with S&S cylinders and pistons. Note that this flywheel assembly is not recommended for compression ratios higher than 10.0:1 for Tri Glide or other three-wheel models (including conversions).
