Never lose drive — or brakes — to a slipping pinion again. The genuine ARRMA ARA311009 pinion gear features the clever Safe-D5 design: a D-shaped 5mm bore that positively locks onto the flat of the motor shaft, so power goes to the wheels no matter how hard you send it.

Machined from steel with a 26-tooth, 0.8Mod profile, it's a durable replacement or gearing option for ARRMA's 3S-class vehicles. Fitting a larger pinion raises top speed; a smaller one adds punch and keeps temperatures down.
