The Tamiya 18T Pinion Gear is a practical part aimed at improving torque transfer in 540 motor RC cars. It is compatible with Grasshopper family models and suits hobbyists who want dependable, no-nonsense components.

Where this pinion works best

Engineered for a range of Tamiya kits, this pinion fits many Grasshopper variants and similar baselines. It handles casual running and club-level sessions while maintaining consistent contact with the spur gear.

Installation pointers for tuners
