Overview
This 9 tooth straight cut differential pinion is the CNC machined input gear for the Tekno RC NT48 nitro truggy differential. It meshes with the diff ring gear to turn driveshaft rotation into axle drive, so its condition sets how efficiently and how quietly the drivetrain runs.
Straight cut gears carry load across the full tooth face instead of sliding, which is why Tekno RC uses the profile in its high-efficiency diff gear sets. A worn or chipped pinion costs you drive and will quickly damage the ring gear it runs against.
Key Features
- Genuine Tekno RC differential pinion gear
- 9 tooth count
- Straight cut tooth profile for drivetrain efficiency
- CNC machined to Tekno RC specification
- Designed for the NT48 differential
Performance Benefits
- Straight cut teeth reduce drivetrain drag and power loss
- Quieter diff operation than bevel-style gearing
- CNC machining gives consistent, repeatable gear mesh
- Replacing a worn pinion protects the matching ring gear
Usage Notes
- Replace the pinion and ring gear together whenever possible
- Set mesh carefully: too tight adds drag, too loose strips teeth
- Rebuild the diff with fresh fluid and seals while it is open
- Follow your Tekno RC manual for shimming and assembly order
