22205-88A Keith Black Cast Hypereutectic Pistons

Keith Black brings his decades of drag-racing expertise to your Sportster with these hypereutectic cast pistons. Using a specialized aluminum alloy, these pistons are designed to be lightweight while maintaining tighter running tolerances than traditional forged pistons. This results in a quieter top end and reduced oil consumption. The high ring placement is specifically engineered to combat detonation and improve power. This kit is sold as a set and includes two pistons, Hastings chrome moly rings, wrist pins, and circlips. These pistons fit Sportster and Tube frame models and are a direct replacement for OEM 22205-88A, offering a high-quality upgrade for any performance-minded rebuild.
