Description
These Federal Mogul Performance rod bearings are intended for the small block Olds crankshaft that has been stroked or destroked with a finished rod journal size of 2.100. By stroking or destroking these olds small block crankshafts allows for an increased or decrease in cubic inches. Reduction of the rod journal size from 2.125 to 2.1 reduces bearing speed, and bearing surface area. These bearings shown here are intended for Aluminum rods only with a finished rod journal size of 2.1 inches.
