Durable pinion gear performance for RC drivetrains

The Tamiya 54578 06 Module Hard Coated Aluminum Pinion Gear 25T OP-1578 is a serviceable replacement pinion aimed at hobbyists who want reliable gear engagement without adding unnecessary weight. Machined from aluminium, it balances strength and lightness for everyday RC running.

Build details and fitment

The hard coating on this pinion improves surface toughness and helps resist wear under regular use. Rounded tooth profiles reduce friction and support smoother power transfer through the gearbox. It mates with 06 Module spur gears commonly used in 1/10 scale setups.

Whats in the box

  • Hard Coated 25T Aluminum Pinion Gear x1
  • 3mm Grub Screw x1

Is this pinion suitable for typical 1/10 scale off-road buggies?

Yes. The 25T tooth count and 06 Module profile are compatible with many 1/10 scale off-road buggies that use the same module spur gears, but always check mesh and clearance before running.

How does the hard coating change service life?

The coating increases surface hardness which slows wear on the teeth under normal driving loads, helping retain accurate tooth profiles longer than uncoated aluminium.

Any tips for installing the grub screw?

Lightly thread the grub screw and set pinion depth to achieve a snug, even mesh. Apply a small amount of thread locker if you run on rough terrain, but avoid overtightening which can strip the set screw.
