Fine-Tune Your 1/8th Off-Road Drivetrain with HOBBYWING 15T

The HOBBYWING 15T 5mm M1 steel pinion gear is a reliable upgrade for 1/8th scale off-road buggies and truggies used in club racing and weekend bashing. Manufactured from 40CR steel, it is made to hold accurate tooth geometry under load for consistent performance.

How Pinion Choice Changes Drive Characteristics

Swapping pinion tooth counts directly changes acceleration and top speed. Lower tooth counts increase torque for steep or loose conditions, while higher counts raise rpm and top speed on flat track sections.

Fitment and Technical Fit

This 15T pinion has a 5mm bore and a 1.0mm modulus, matching common 1/8th off-road motor shafts and gear setups. Its hardened steel construction helps reduce wear so you get repeatable gearing across events.

Will this pinion work with my 1/8th brushless motor setup?

It fits most 1/8th scale brushless systems that use a 5mm motor shaft and M1 gear profile. Always verify your motor shaft diameter and the required modulus before installing.

How do I change gearing for more speed?

Increase the pinion tooth count step by step to raise top speed, and monitor motor temperature and gear mesh after each change to avoid overheating or premature wear.

Do I need to modify the motor or gearbox to fit?

No machining is normally required if your shaft is 5mm and the gearbox accepts M1 modulus pinions. Fit the gear securely with proper mesh and a tightened set screw.
