The Compu-Fire 1084 gear sets are engineered to increase the starter motor torque by lowering the gear ratio of the pinion gear to the clutch ring gear. When used as a replacement for the 9:66 ratio gear sets, a 15% increase in torque is obtained. They are also used as replacements for the weak 10:102 ratio gear sets which are prone to breaking on late model Big Twins.
