Common questions
What Harley engines are these pistons designed for?

Are these forged or cast pistons?
These are forged pistons, which are significantly stronger and more durable than cast pistons. This makes them ideal for high-performance applications and engines that see hard use.
Will I need machine shop work to install these pistons?

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!
