This COMP Cams bronze distributor gear is machined from AMPCO-45 extruded aluminum bronze with 5% nickel for high-strength tooth design. It fits steel roller camshaft installations where a stock cast iron gear is incompatible; specified for Chrysler V8 273–360 LA and Donovan V8 applications and accepts a 0.484" shaft diameter while resisting wear under high oil pressure.
