The Yokomo BM-4820A Hard Steel Pinion Gear brings durable 48 pitch, 20-tooth gearing to hobbyists who want long life and steady performance. Built from hard steel, it resists wear and keeps consistent mesh for smooth power transfer across different setups.
This pinion suits many Yokomo chassis types, including the DP-YD2 series and similar platforms. Its simple 48 pitch and 20-tooth spec make it a practical swap when changing gear ratios or moving parts between cars.
