Clevite H-Series Performance Connecting Rod Bearing Set CB663HN10 for Select GM/AM General 1980-2015

Fits select 1980-2015 AM General, Buick, Cadillac, Checker, and Chevrolet models.

Clevite H-Series performance bearings are engineered specifically for high-stress competition engines and medium to high-RPM applications. These bearings feature a hardened steel back for superior support and a thin overlay for maximum fatigue resistance. Designed with high crush and medium eccentricity, they ensure optimized bearing retention and consistent oil film thickness under heavy loads.

The H-Series is manufactured without flash plating to facilitate better seating and thermal transfer. This specific design also provides the necessary clearance for crankshafts with oversize fillets, a common requirement in performance and racing builds. Whether you are rebuilding a classic small block or a late-model LS engine, these bearings provide the tolerances required for professional engine assembly.
