For Sportster riders looking for high-performance street or race reliability, these Keith Black forged alloy pistons are a serious upgrade. They are manufactured from 4032 alloy with an 11% silicon content, a combination that allows the piston to flex under extreme conditions like detonation or pre-ignition without cracking. Because of the specific expansion rates of this forged alloy, they require a slightly wider piston-to-wall clearance than hypereutectic alternatives. This kit is sold as a set and comes complete with high-quality Hastings piston rings, wrist pins, and spiral lock rings. Whether you're running a high-compression setup or even a nitrous-equipped bike, these pistons provide the durability needed for demanding applications.
