Clevite H-Series performance bearings are engineered specifically for engines operating in the medium to high RPM range. These bearings feature a hardened steel back and a thin overlay to provide the durability required for performance applications. With a medium level of eccentricity and high crush, they are designed to accommodate crankshafts with oversize fillets while ensuring a precise, secure fit in the housing.

Unlike standard bearings, the H-Series is manufactured without flash plating to allow for better seating during installation. This makes them a preferred choice for high-load builds where component reliability is critical. These bearings are designed to handle the stresses of performance environments while maintaining consistent oil film thickness.
