Overview
Fine-tune your gearing with the Hot Racing 17T 0.5 Module Hardened Steel Pinion Gear. CNC-machined from hardened steel with a blackened finish for maximum durability, this 17-tooth pinion is the ideal middle-ground choice for racers and bashers seeking balanced top-speed and acceleration tuning in any 0.5 mod drivetrain.
The 1/8" (3.2mm) bore matches the most common standard motor shafts in compact RC platforms, while the hardened steel construction guarantees long-term reliability under heavy throttle and brushless power.
Key Features
- Hardened steel construction with blackened finish
- 17-tooth count for balanced gear-ratio tuning
- 0.5 module (Mod) gear pitch
- 1/8" (3.2mm) bore for standard motor shafts
- 3mm set screw included for secure installation
Performance Benefits
- Hardened steel resists wear and stripping under high torque
- Balanced top-speed and acceleration with the 17-tooth ratio
- Consistent power transfer run after run
- Far longer service life than aluminum pinions
Usage Notes
Compatible with 2mm motor shafts when used with the Hot Racing CSG182R08 motor adapter. Verify gear mesh by spinning the drivetrain by hand — there should be a small amount of backlash with no binding. Apply removable thread-locker to the set screw during installation.
