Hobbywing 21T pinion built for rugged use

The Hobbywing 21T 5mm 48P Steel Pinion Gear is intended to enhance drivetrain durability in 1/10th scale models. Made from hard anodized chrome steel and rated around 48-53HRC, it gives a good balance of toughness and gear accuracy for heavy-duty runs.

Fine-Tune Torque Versus Top Speed

Swapping pinions is a straightforward way to change vehicle behaviour. Use fewer teeth for stronger acceleration and climbing, or more teeth to push higher maximum speed, depending on the terrain and your setup.

Specifications

  • Bore Diameter: 5mm
  • Modulus: 0.53
  • Material: 40CR Steel

Compatibility Notes

This 21T pinion matches a wide selection of 1/10th scale rigs, such as the TRAXXAS 1/10 SLASH 4x4, and is suitable for short course, monster trucks and similar vehicles that require a 48P, 5mm bore pinion.

It fits motors with a 5mm shaft and a 48P spur gear. Confirm your motor shaft size and tooth pitch before ordering.
Steel pins run hot under heavy load; monitor motor and pinion temperature after changes and ensure correct mesh to limit heat build-up.
Light thread locker can be used on a grub/set screw to prevent loosening, but avoid excess which can make future removal difficult.
