Rugged 2-Speed Upgrade for Nitrage 5.2

The Tamiya 54003 2-Speed Transmission is built as a bolt-on solution for Nitrage 5.2 drivers who want stronger gear life and more controlled shifts. It takes the place of the centre differential so installation stays straightforward. The hook-type clutch provides repeatable engagement and the sintered metal counter gear stands up to heavy running. Shift timing can be easily adjusted via the cam holder screw for quick trackside tuning.

Specifications

1st Gear: 48T
2nd Gear: 43T
Counter Gear (2-Speed Pinion): 23T/29T
Includes: Cup Joint, Ball Bearing, Hex Wrench (2mm, 2.5mm), Cam Holder, Main Shaft, 6mm Lock Nut & Diaphragm Spring

How long does installation typically take?

Most experienced hobbyists can install Tamiya 54003 in under an hour once the old centre differential is removed, thanks to the bolt-on design and included hex wrenches.

Will the gear ratios affect acceleration or top speed?

The 48T and 43T gears provide a balance between off-the-line acceleration and higher top speed. The counter gear options 23T/29T change final drive feel, so test both if you want a different response.

Is the kit compatible with standard electronics?

Yes. The transmission is a mechanical upgrade and works with standard speed controllers and motors used in Nitrage 5.2 models, but check motor pinion fit and clearance after installation.
