For riders looking to rebuild or upgrade their Sportster or XB engine, these Keith Black hypereutectic pistons offer race-proven technology in a street-ready package. The unique alloy used in these pistons provides excellent heat resistance and allows for very tight tolerances, which translates to more power and a quieter-running motor. This kit is sold as a set and includes two pistons, Hastings chrome-moly rings, pins, and circlips. The high ring placement design helps to increase efficiency and reduce the risk of detonation. Whether you are doing a standard refresh or a performance build, these pistons provide the durability and precision needed for a high-output Harley-Davidson engine.
