LOWER ROD BEARING LARGE JOURNAL STANDARD

Clevite H-Series Lower Rod Bearing Large Journal Standard

This Clevite H-Series lower connecting-rod bearing is designed for Chevrolet small-block and GM LS engines using a standard 2.100" large-journal crankshaft.

Its tri-metal construction combines a hardened steel backing, high crush and a thin bearing overlay to provide secure seating and reliable load support in demanding competition engines. The narrowed profile and enlarged side chamfers provide additional clearance for performance crankshafts with increased journal fillets.

This bearing maintains standard oil clearance and is uncoated. It is supplied individually as one lower shell, making it suitable for targeted replacement during engine inspection, servicing or precision rebuild work.
