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 Pack is a comprehensive performance upgrade that combines big-bore cylinders with matched pistons, a performance cam, cam plate, and oil pump. This kit is engineered to build reliable horsepower for your Harley-Davidson without the need for a full custom engine build, offering significant gains at a reasonable price point. It's designed as a complete bolt-together solution for riders seeking serious 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!
