More info

These Traxxas 17T Pinion Gear parts are a straightforward way to upgrade drivetrain durability and tuning options. Machined from hardened steel, the 17-tooth, 32-pitch design resists wear while fitting standard 3 mm motor shafts; a included set screw keeps the pinion locked in place during hard driving.

Key Features

  • Hardened-steel construction for extended service life under load.
  • 17-tooth, 32-pitch sizing for precise engagement with matching gears.
  • 3 mm bore fits standard 3 mm motor shafts common on Traxxas models.
  • Includes set screw for secure mounting and reliable power transfer.
  • Tuning-friendly — swapping this pinion helps balance acceleration and top speed for different tracks or terrain.

Why Choose This Product

The Traxxas 17T Pinion Gear is a simple, effective upgrade or replacement when you need a tougher pinion that still lets you fine-tune gearing. It’s a practical choice for weekend bashing, club racing, or any build where consistent gear engagement and longevity matter.
