Upgrade Gearing with HOBBYWING 15T Pinion

The HOBBYWING 15T 5mm M1 steel pinion gear is a solid choice for racers and hobbyists wanting predictable gear ratios in 1/8th scale off-road vehicles. Produced from 40CR steel, it resists deformation during high torque runs.

Practical Effects of Pinion Size

Selecting the right pinion tooth count affects acceleration and maximum speed. Lower teeth increase torque for climbs and loose tracks, while more teeth favour higher top speed on long straights.

Compatibility Details

This 15T pinion has a 5mm bore and a 1.0mm modulus that match common 1/8th off-road motor and gearbox setups. The hardened steel makes it durable for repeated race day or park sessions.

Will the pinion handle high power brushless motors?

The 40CR steel material provides strength for high torque loads, but proper gear mesh and motor temperature monitoring are still essential to avoid premature wear.

Which tooth counts work well with this 15T option?

Common pinion ranges for 1/8th off-road span from lower teeth for offroad torque to higher for track speed. Pick incremental changes and test to find the best compromise for your track.

Do I need shims or spacers to fit?

Most installs do not require special shims if your gearbox and motor plate match standard 1/8th spacing, but fine tuning gear mesh with shims is recommended for quiet, efficient running.
