Precision Pinion for 1/8 Off-Road Models

The HOBBYWING 15T 5mm M1 steel pinion gear is tailored for 1/8th off-road buggies and truggies where reliable gearing matters. Constructed from 40CR steel, it maintains tooth integrity under demanding conditions.

Gearing Effects Explained

Altering the pinion tooth count shifts the balance between torque and top speed. A smaller pinion improves low end pull for rough or technical layouts, while a larger pinion increases outright speed on open sections.

Fitment and Durability

This 15T pinion uses a 5mm bore with a 1.0mm modulus and will fit gear trains built to those specs. Its hardened steel composition helps extend service life for both competitive and hobby use.

Can I fit this pinion without special tools?

Basic hand tools are sufficient for fitting on a 5mm shaft, but use a torque driver for the set screw and confirm gear mesh with feeler or paper method to avoid binding.

Is this pinion suitable for both racing and bashing?

Yes. The 40CR steel gives durability for hard use, making it appropriate for both competitive racing and more aggressive bashing sessions, provided fitment and mesh are correct.

How should I care for the pinion to extend life?

Keep the gear free of grit, inspect teeth after crashes, and ensure correct mesh and lubrication on mating gears to maximise service life.
