Overview
Push your Traxxas 2WD truck even faster with the Hot Racing 73T 48-Pitch Hardened Steel Spur Gear. CNC-machined from lightweight hardened steel and finished with sharp orange-anodized countersunk washers, this 73-tooth, 48-pitch spur delivers a faster final drive ratio than the 75T or 76T options for drivers chasing higher top speeds.
Hardened steel construction handles brushless torque loads without breaking down, while the aggressive lower tooth count delivers a useful top-speed boost when paired with the right pinion.
Key Features
- CNC-machined lightweight hardened steel
- 73 teeth, 48 pitch
- Orange anodized countersunk washers
- Faster final drive than 75T or 76T options
- Direct replacement for stock nylon spur
Performance Benefits
- Faster top speed than higher-tooth spurs (with same pinion)
- Eliminates stripped-spur failures under brushless power
- Long service life
- Lightweight design preserves drivetrain efficiency
Usage Notes
The 73T tooth count requires a larger pinion gear than stock — typical pinion range is 25-34T depending on motor and ESC. Monitor temperatures: motor should not exceed 180°F (82°C); ESC should not exceed 160°F (71°C). Higher temps shorten motor and ESC life.
