Overview
Get a faster final drive ratio plus bulletproof spur durability on your Traxxas TRX-4 with the Hot Racing 39T 32-Pitch Hardened Steel Spur Gear. CNC-machined and lightened from hardened steel, this 39-tooth, 32-pitch (0.8 mod) spur is engineered for high-power brushless systems where stock nylon spurs strip under load.
The lower 39-tooth count vs. the 45T or 38T options provides a useful top-speed boost while still maintaining the bulletproof reliability of 32-pitch hardened steel teeth. Black oxide coating delivers corrosion protection and a clean stealth look.
Key Features
- CNC-machined hardened steel, lightened design
- Black oxide coating for durability and corrosion resistance
- Rugged 32-pitch (0.8 module) teeth
- 39-tooth count for faster final drive vs. higher-tooth options
- Direct replacement for factory plastic gear
Performance Benefits
- Higher top speed than 45T spur (with same pinion)
- Eliminates stripped-spur failures under brushless power
- 32-pitch teeth deliver maximum tooth strength
- Long service life
Usage Notes
Must be used with a matching 32-pitch (0.8 module) pinion gear. Apply removable thread-locker on mounting hardware and verify proper gear mesh after installation.
