Tamiya TT02 Compatible 42 Pitch Delrin Spur Gear 70T DTT2B070T by GPM  [DTT2B070T]

Tuning impact of a 70T Delrin spur on TT02 setups

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.

Changing to a 70T spur will reduce final drive speed and increase torque at the wheels versus lower tooth counts. Use this characteristic to tune for better acceleration or to ease load on the motor in technical sections. Always select a pinion that complements the new final ratio.

Before running, confirm pinion alignment, inspect bearings, and set mesh correctly. Proper tuning requires balancing spur and pinion choices with motor timing and ESC settings for the best on-track performance.
