Quality pinion gear, fits tightly onto my Element Ultra Torque motor. Stock pinion gear immediately showed wear after one day of use, and I could hear the raggedness of the gearbox when shooting. This Echo 1 pinion gear is standing up well so far on 13:1 gears with an m120 spring. Seems like it will last a while.
Steel pinion gear
Fits on Element motor
Shows little wear on 13:1 gears and m120 spring
MAKE SURE YOUR MOTOR IS D TYPE, NOT O TYPE
Tight fit, took full weight pressing down on hard surface to get on
Overall, good pinion gear, highly recommended.
