Traxxas 21T Pinion gear with set screw, part #2421.

Original Traxxas pinion gear with 48-pitch that fits on a wide variety of Traxxas radio controlled car models with 48-pitch spur gears and 3mm motor shafts. Changing the pinion gears allows the driver to fine-tune the accelleration and top speed of the car - larger gears will result in higher top speed while a smaller gear provide more torque and acceleration.

This 21T is the standard pinion gear on the 4-Tec 2.0, Summit 1/16 and Stampede.

  • Traxxas 4-Tec 2.0,
