These high-performance pistons are engineered as a direct replacement for stock components, providing a solid foundation for a top-end overhaul.

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!
