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, bolt-on upgrade kit designed to deliver significant horsepower gains on your Harley-Davidson engine. It combines 4.32-inch big-bore cylinders with matched pistons, a performance cam, cam plate, and an oil pump, creating a reliable power package without requiring extensive internal engine modifications.

When you're ready to take your Harley's performance to the next level, the S&S Cycle Power Pack provides a complete solution.

Installation Considerations
While the S&S Cycle Power Pack is designed for straightforward installation as a complete kit, it's important to recognize that this is a major engine overhaul. Disassembly of the cam chest and top end will be required. For optimal results and to ensure the longevity of your engine, professional installation is strongly recommended. Additionally, a proper fuel management system and dyno tune will be necessary to maximize the performance gains from this upgrade.

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!
