Precision Spur Gearing for the TA04 Chassis

The Tamiya 50873 spur gear kit is supplied in durable black nylon and tailored for use with the TA04 chassis. With 112, 120 and 128 tooth spurs included, the set enables precise changes to gear ratio so you can refine acceleration, top speed and overall drivetrain behaviour according to circuit conditions.

Choose the 128 tooth spur to raise the effective gear ratio for improved top speed, provided your motor and pinion selection support the change without overheating.
Nylon spurs are generally quieter and kinder to pinions than metal gears; they also absorb shock better, though you should still monitor wear on heavy-use cars.
After changing spurs, recheck pinion mesh, ensure there is no binding, and test the car at low speed to confirm smooth engagement before returning to full power.
