The COMP Cams bronze distributor gear (.491" I.D.) is machined from AMPCO-45 extruded aluminum bronze with 5% nickel to work with steel roller camshafts. Its high-strength tooth design resists wear even with high-pressure oil pumps. This gear fits Oldsmobile V8 engines covering 260–455 cubic inches and accepts a 0.491" distributor shaft, serving as a durable replacement where cast iron gears fail.
