Description
Building serious displacement on your Twin Cam requires pistons engineered for the exact compression ratio and durability your build demands. S&S Cycle’s 92-1204 kit delivers precision-forged pistons that maintain consistent ring seal and reduce detonation risk across the RPM band. This is the foundation that separates reliable high-output motors from ones headed for catastrophic failure.
