Key Features

- Made as a direct replacement for rear differential pinion wear and damage, making repairs straightforward.
- Designed to pair with the 7779 42-tooth differential ring gear to preserve the correct gear ratio and drivetrain timing.
- Simplifies maintenance by returning the rear differential to factory-spec engagement without shimming changes.
Why Choose This Product
This Traxxas Pinion Gear 13-Tooth Rear Differential is a practical spare for anyone who runs their rig hard or keeps older trucks in service. Use it when you hear gear noise, see chipped teeth, or during a full differential rebuild to get the rear drivetrain back to smooth operation.
