ARRMA 22T MOD 0.5 CNC 2.3mm Bore Grom RC Pinion Gear - ARA311208

The ARRMA ARA311208 pinion gear is a 22-tooth, MOD 0.5 CNC-machined replacement gear designed specifically for the ARRMA Grom mini RC car. With a 2.3mm bore, this pinion gear is a direct-fit part for Grom models including the ARA2102T1, ARA2106T1, and ARA2106T2. CNC machining ensures consistent tooth geometry and a precise bore fit, which matters when you're reinstalling a drivetrain component on a small-scale RC car where tolerances are tight. If your existing pinion has stripped teeth or worn flanks, this is the correct OEM-spec replacement part to get your Grom back on track.
