This is a steel helical differential ring pinion overdrive 33T/12T gear set for 1/10 scale Traxxas TRX-4 by Hot Racing.
- Precision machined helical spiral cut gears offer inherently greater strength and smooth operation than the factory straight cut bevel gears.
- High carbon steel construction.
- Less vibration, less noise, less wear then stock straight cut bevel gears.
- 33T/12T provides 9% overdrive (vs stock 34T/11T) increases the wheel speed and is commonly used in the front end for digs.
- Works on front or rear. Use cases are typically front and rear at the same time, or front only to increase front digs.
