ARRMA 21T Mod1 Safe-D5 RC Pinion Gear - ARA310968

The ARRMA ARA310968 is a 21-tooth Mod1 pinion gear with a Safe-D5 bore, designed as a direct-fit spare or replacement gear for a wide range of ARRMA brushless electric vehicles. The Safe-D5 interface uses a flat-sided 5mm bore that locks positively onto compatible ARRMA motor shafts, eliminating slippage without the need for a grub screw on the shaft flat alone. If you're rebuilding the drivetrain on an ARRMA Kraton, Notorious, Talion, Typhon, or Infraction, this RC pinion gear is the correct spec part to get you back on the track or bash spot.
