Yokomo PG-4821A 21T Hard Coated Pinion Gear DP48 Track Ready  [PG-4821A]

Precision Pinion for Smooth Gear Mesh

The Yokomo PG-4821A pinion features a hard-coated aluminum body that balances durability with light weight for clean drivetrain behaviour. The 21-tooth layout and 48 pitch standard match common 1/10 spur gears for predictable power delivery.

Durability Without Excess Weight

The hard treatment on the gear face reduces abrasion from the mating spur, while the aluminum core helps reduce rotating inertia. These traits combine to keep performance consistent over many running sessions.

Compatibility and Setup Advice

Ideal for 1/10 scale models using 48 pitch gearing, the Yokomo PG-4821A installs easily when paired with the correct spur. Verify tooth engagement and motor shaft fit before track use to avoid premature wear.
