Fine-Tune Your Nitrage 5.2 with a 2-Speed Unit

The Tamiya 54003 2-Speed Transmission provides a bolt-in upgrade for Nitrage 5.2 cars looking for finer control over acceleration and higher maximum speed. It replaces the centre differential to simplify the swap and reduce build steps. The hook-type clutch delivers crisp, repeatable shifts while the sintered metal counter gear boosts resistance to wear. Shift timing is adjustable via the cam holder screw for precise tuning.

What should I check after my first run?

After the initial runs check gear mesh, re-tighten lock nuts and verify the cam holder screw has not shifted. Reinspect bearings and the diaphragm spring for correct seating.

Can the shift point be softened or sharpened?

Yes. Adjusting the cam holder screw alters how quickly the clutch engages, allowing you to soften or sharpen shift feel to match driving style.

Are spare parts available for the kit?

Common service parts like bearings and diaphragm springs are available separately from suppliers. Keep spares for quick repairs after heavy use.
