One of the first requirements when installing a steel roller cam
is the addition of a bronze distributor gear. A stock cast iron
gear is not compatible with a steel camshaft. COMP Cams® gears
are machined from AMPCO-45 extruded aluminum bronze with 5%
Nickel added. These gears feature a high-strength tooth design
that resists wear even when used with high pressure oil pumps.
These extra tough gears are the answer when higher mechanical
properties are demanded.
