Upgrade Gears for TA-04 Chassis

RC drivers wanting reliable pinion options can rely on the Tamiya 53421 Aluminum Pinion Gear Set for straightforward ratio tweaks. The dual pinion pack is cut for TA-04 models and supports precise engagement for consistent performance.

Solid Aluminium Finish

These pinions are machined from aluminium to reduce wear while keeping weight low for responsive drivetrain feel. The kit includes both 42T and 43T gears so you can experiment with gearing balance between acceleration and speed.

Easy to Fit

Installation is made easy with the supplied allen key and set screws, letting builders swap pinions without fuss. Compatibility is centred on TA-04 but the 48P metric profile means they can fit many other 48P gearsets as well.
