Overview
This 40 tooth differential ring gear uses Tekno RC's true straight cut design for maximum drivetrain efficiency. It is CNC machined from hardened steel and runs smoother and quieter than Tekno RC's standard gears, making it a genuine performance upgrade as well as a replacement part.
Fitment is the NT48 nitro truggy front differential, and the ET48 electric truggy front or rear differential. Gear mesh and wear in the diff have a direct effect on how much of your engine or motor power reaches the wheels.
Key Features
- True straight cut design for maximum efficiency
- Smoother and quieter than Tekno RC's standard gears
- CNC hardened steel construction
- 40 tooth count
- Fits NT48 front and ET48 front or rear differentials
Performance Benefits
- Straight cut teeth reduce drivetrain losses compared with bevel designs
- Quieter running drivetrain with less gear whine
- Hardened steel resists tooth wear under 1/8 truggy loads
- CNC machining delivers consistent, repeatable mesh
Usage Notes
- Replace the ring gear and its matching diff pinion as a pair for best mesh
- Set diff gear mesh carefully; too tight increases drag, too loose strips teeth
- Rebuild the differential with fresh diff fluid and seals while it is apart
- Follow your Tekno RC manual for diff assembly and shim placement
