ARRMA 26T 0.8 Mod 4x4 BLX 3S RC Pinion Gear - ARAC7879

The ARRMA ARAC7879 pinion gear is a 26-tooth, 0.8 module replacement drivetrain component designed for ARRMA 4x4 BLX 3S models. Running a brushless 3S setup puts significant load through the drivetrain, and keeping a correctly specced pinion gear on hand means you can get back on track quickly after hard use. This is a direct OEM-spec part, so fitment and gear mesh on compatible ARRMA vehicles are exactly as the manufacturer intended.
