About S&S Cycle

S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.

The S&S Cycle Power Package is a comprehensive big-bore engine build kit designed to deliver reliable horsepower gains for your Harley-Davidson. It combines 4.32" cylinders with a matched cam, cam plate, oil pump, and all supporting components, engineered as an integrated system for optimal performance.

100 kit is sick! 10/5/1 compression is perfect for the 585 cams. Not going to burn the tires unless you bounce it, but at 2.7 K it pulls like a freight train. Super fun! Thanks S&S!
