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 complete engine transformation kit, meticulously designed to unlock high-performance horsepower from your Harley-Davidson engine. It combines big-bore cylinders with a matched performance cam, cam plate, and a high-volume oil pump, alongside all supporting components. This integrated system ensures enhanced power delivery while maintaining the crucial reliability that riders demand.

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!
