Tamiya 18-19T RC Pinion Gear - 50355

The Tamiya 50355 pinion gear set provides 18-tooth and 19-tooth steel pinion gears for use with Tamiya RC car drivetrains. Pinion gears are a core part of the gear mesh that transfers motor output to the drivetrain, and selecting the right tooth count directly affects your final drive ratio. The TAM50355 set gives you two options in one pack, making it straightforward to tune gear ratios or keep a spare on hand without ordering separately.

Key Features

• Includes both an 18T and a 19T pinion gear, giving you two gear ratio options in a single purchase
• A higher tooth count (19T) lowers the overall drive ratio for higher top speed, while the 18T offers slightly more torque and acceleration
• Designed to Tamiya's standard fitment specifications for consistent mesh with compatible Tamiya spur gears
• Suitable as a direct replacement when a pinion gear is worn, stripped, or lost during drivetrain servicing

Compatible With

• Tamiya RC cars and buggies using a compatible motor pinion fitment — check your model's manual or parts list to confirm tooth count and bore size compatibility before fitting

• 1x 18-tooth pinion gear
