DELTAWALL
High Eccentricity
Deltawall bearings are only available for the early and late model small block Chevrolet connecting rods. These bearings incorporate a patented design which produces a tighter clearance in the upper or rod half bearing to spread firing loads over more of the bearing surface while providing greater clearance in the lower or cap half bearing to allow for rod bore close-in and to maintain oil flow for cool running. The upper and lower bearing shells differ in centreline wall thickness by .002”. the upper is .001” thicker than a standard equal wall bearing and the lower is .001” thinner than an equal wall design for the same application.
Use Deltawall rod bearings in engines which operate over a broad range of RPMs with only brief periods of operation at maximum RPM; such as engines running on road courses or short tracks where engine pulls hard through mid range.
