These are double hardened and feature two M4 setscrew holes (for long shafts) to secure the pinion to the motor shaft. Using these pinions allows the use of ESC/motor brakes on your Tekno converted vehicle. You can also use these in conjunction with mechanical brakes. All options are now available with one conversion.
Tekno RC V3 Motor Plates for Long Shank Pinions (TKR40002A) may be required if using Losi 8B, 8T, or AE RC8. Mugen, Jammin, Hot Bodies and RC8T do not require long shank pinion plates.
