S&S CYCLE Flywheel Assembly — 117", 114", 4-1/2" stroke – 18-23 Softail, 17-23 Touring, 17-23 Trike, 17-23 CVO

Precision flywheel assembly engineered for gear drive camshafts and consistent balance through precision machining.

Factory-installed balance gear simplifies installation, and the strong assembly eliminates the need to weld the crankpin.

Heat treated 4140 material delivers improved hardness and roughly twice the strength of stock components.

Connecting rods are optimized using finite element analysis (FEA) to remove weak spots; the kit includes flywheel, crankpin and connecting rods.

Made in the USA. Not recommended for compression ratios higher than 10.0:1 for Tri Glide or other three wheel models (including conversion). Displacement is used with S&S cylinders and pistons.

Built for dependable performance on both the street and track. 🔧
