CB1643H Clevite 77 H Series Rod Bearings - Mitsubishi 4G63 - STD Size

H series bearings have a medium level of eccentricity, high crush and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with .001 extra clearance are available for standard size shafts and carry the suffix HX (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range.
