Tamiya TT02/TT02B Compatible Delrin Spur 42P 70T DTT2B070T by GPM  [DTT2B070T]

Compatibility and gearbox fit for the TT02 70T spur

This Delrin spur gear is a scale RC replacement intended for the Tamiya TT02 platform and TT02B variant, supplied as 1pcs and specified as 42 pitch, 70T. It is an aftermarket gear for hobby drivetrain use only and is not for real vehicle applications.

Confirm that your gearbox uses 42 pitch gearing and that the mounting interface matches the original spur. Clean the gearbox, inspect the pinion and bearings, and set correct mesh before normal running to ensure reliable fitment.

The 70T count alters the final drive ratio compared with smaller spurs commonly fitted to TT02 cars. Pair the spur with a suitable pinion and re-evaluate motor temperatures and performance after installation to validate compatibility with your setup.
