UPPER ROD BEARING LARGE JOURNAL EXTRA CLEARANCE
Clevite H-Series Upper Rod Bearing Large Journal Standard 0.001" Extra Clearance
This Clevite H-Series upper connecting rod bearing is designed for high-performance Chevrolet small-block and GM LS engine applications using the large 2.100" rod journal.
The bearing has a reduced wall thickness to provide 0.001" additional oil clearance while retaining a standard-size crankshaft journal fitment. Its narrowed profile and enlarged side chamfers provide additional clearance for performance crankshafts with increased journal fillets.
H-Series bearings feature a tri-metal construction, hardened steel backing, high crush and a thin overlay. These characteristics make the bearing suitable for competition engines operating at sustained medium to high RPM.
Supplied individually as one upper bearing shell for targeted engine servicing and rebuilds.
