Everything you expect from S&S
Have installed this kit on multiple bikes. S&S knows what they’re doing.
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.
S&S Cycle Power Packs are premium piston sets for Harley-Davidson engines that increase displacement and horsepower compared to stock pistons. These are direct bolt-in replacements engineered for high-performance builds and stroker applications.
When you're pushing the limits of your Harley-Davidson V-twin, an S&S Cycle High-Performance Piston Set provides the robust foundation you need. Engineered for serious builds, these pistons are designed to handle the demands of increased displacement and higher compression ratios. They offer a direct bolt-in replacement for your stock pistons, simplifying the upgrade path for riders chasing more power and reliability.
These S&S pistons are not just replacements; they are upgrades. Crafted with precision, they are ideal for riders looking to maximize their engine's potential, whether through a simple top-end refresh or a full stroker build. Pairing these pistons with other S&S performance components like cams and cylinder heads will unlock the full performance capabilities of your Harley-Davidson Touring, Softail, or Dyna.
What displacement increase will I see with these pistons?
Displacement gain depends on your engine's stroke and bore combination. We recommend checking S&S technical specifications for your specific engine model.
Do I need to get my engine bored or honed?
That depends on your engine's current bore size and which S&S piston set you order. Consult S&S sizing guides or your engine builder to confirm.
Are these pistons forged or cast?
S&S manufactures high-performance pistons using advanced processes to ensure strength and durability, suitable for demanding V-twin applications.

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!
