      RC spur gears to pair with your pinion and set the gear ratio.

      An RC spur gear is the large gear that the pinion drives, and together they set your gear ratio. This category covers spur gears in the common pitches and tooth counts, so you can tune the drivetrain and replace worn gears.Match the pitch to your pinion. See pinions and hardware in RC car accessories.

      Frequent Questions & Answers
      What does an RC spur gear do?

      It is the large gear driven by the pinion. The pinion and spur tooth counts together set the gear ratio, which affects speed and acceleration.

      How do I choose a spur gear?

      Match its pitch to your pinion (such as 48dp or Mod 1), then use the tooth count with the pinion to set your ratio.

      When should I replace a spur gear?

      Replace it if teeth are chipped, worn or stripped. A damaged spur skips under power and can wreck the pinion too.
