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

Lightweight Pinion Options for Precision Tuning

The Tamiya 53407 Aluminium Pinion Gear Set gives racers two close-ratio options to refine gearing. With a 38-tooth and a 39-tooth pinion included, you can dial in acceleration or top speed depending on conditions. The aluminium construction keeps rotating mass low while providing dependable engagement.

Feature Highlights

• Material: Lightweight aluminium provides a good strength-to-weight compromise for track and club use.
• Compatibility: Designed to fit many Tamiya platforms such as TA04 and TB-01 and other models that accept 0.4 M pitch pinions.
• Pitch: 0.4 M (48P metric) pitch for correct engagement with compatible spur gears.

Practical Installation Notes

Installation is simple when the motor mount is secure. Slide the pinion on, tighten the supplied grub screws with the included allen key, and set the mesh so there is minimal play without binding. Regular checks after running sessions will help avoid premature wear.
