Overview
The Robinson Racing 43-Tooth Aluminum Pro Pinion Gear combines lightweight performance with exceptional durability. Precision machined from aerospace-grade 7075 aluminum and finished with a super-hard black anodized coating, this pinion gear delivers professional-level performance for competitive RC applications.
The hard anodized finish not only hardens the surface but also provides corrosion protection and improved lubricity by reducing friction between the pinion and spur gear. This results in smoother operation, less heat generation, and extended gear life during intense racing sessions.
Key Features
- 7075-T6 aerospace-grade aluminum construction
- Super-hard black anodized finish
- 48 pitch tooth profile
- 1/8" (3.17mm) bore size
