Overview:
Arrma Safe-D5 Mod1 Pinion Gears feature a "D" shaped hole that allows the motor shaft to key inside the pinion gear, eliminating the loss of drive and brakes if the set screws comes loose. This tough steel Pinion Gear is available in multiple tooth count options, allowing you to fine tune the gear ratio. Use the pull down menu above to pick the pinion gear for your application.
