Tamiya 53407 0.4 Aluminum Pinion Gear Set 38T/39T OP-407 - Track Tuning Set  [53407]

Optimise Drive Ratios with Aluminium Pinions

The Tamiya 53407 Aluminium Pinion Gear Set offers two close options so you can tune your gear ratio on the fly. The 38T and 39T pinions let you experiment with acceleration and top-end behaviour. Their aluminium build keeps inertia low while maintaining solid tooth engagement.

Notable Specifications

• Material: Precision machined aluminium for reduced rotating mass and reliable strength.
• Compatibility: Suitable for many Tamiya chassis including TA04 and TB-01 and other models that accept 0.4 M pitch pinions.
• Pitch: 0.4 M (48P metric) pitch ensures compatible meshing with matching spur gears.

Simple Setup and Maintenance

To install, confirm the motor mount is secure, fit the chosen pinion and tighten the supplied grub screws with the included allen key. Set the gear mesh to allow a small amount of clearance so the gears run smoothly, and check mesh and screw tightness periodically.
