## Description

Extra hard high carbon motor pinions are built to last with our hi-performance GEN3 steel slipper units. Made from high carbon steel and then heat treated to increase the hardness of the surface even further. High carbon steel is naturally lower in friction and adhesion than milder grades of steel making these gears ideal for use with metal spur gears. All pinions precision machined and stamped with the number of teeth. One 4 m/M set Screw included. 2 m/M Allen wrench (not included) Fits the 4 m/M set Screw. Can be run on motors using a 5 M/M motor shaft including Traxxas, associated, and Hei models or for any heavy duty application. Tech note: rrp#1200 5 m/M to 1/8 inch reducer sleeve required for 1/8 inch shaft motors.

## Customer Reviews

### ⭐⭐⭐⭐ WIll not fit TRMT 8E...
*by C***0 on August 12, 2018*

I took a chance when buying this. It does appear to be well made with a nice coating and smooth milling, it simply doesnt fit my current project, a Redcat TRMT8E, but may fit others, so I'll hang on to it.

### ⭐⭐⭐ Decent
*by J***N on November 21, 2020*

Great pinions. Have broken a few teeth of them but there pretty cheap. Not much stands up to the 1650kv motor.

### ⭐⭐⭐⭐ It may be perfect for another vehicle
*by B***S on February 22, 2016*

It is thinner than I thought it would be, and that was an issue with my particular application, however that is only for my application. It may be perfect for another vehicle.
