Sturdy 13T Pinion Built for 1/8th Off-Road Use

The Hobbywing 13T Steel Pinion Gear (86040030) is made for demanding 1/8th scale off-road buggies and truggies, manufactured from hard chrome 40CR steel and heat treated to about 48-53HRC for long service life and consistent gear mesh.

Adjusting Torque and Top Speed

Changing the pinion lets you tune the final drive ratio to match track conditions: lower tooth counts give stronger acceleration and hill climbing, while higher counts increase top speed on open straights.

Gear Specifications

Bore Diameter: 5mm
Modulus: 1.0mm
Material: 40CR Steel

Will this pinion fit my 1/8th truggy shaft?

If your truggy uses a 5mm input shaft and compatible gear modulus, this pinion is mechanically compatible, but verify clearance and spline fit before installation.

How does tooth count affect motor load?

A smaller pinion increases torque and current draw under load, while a larger pinion reduces load at low speed but raises top-end RPM; choose based on motor and battery limits.
