Overview
The Hot Racing Steel 17T 32-Pitch Pinion Gear is a hardened-steel, nitride-treated pinion designed for high-torque RC applications. CNC-machined from hardened steel and surface-treated with nitriding for enhanced hardness and corrosion resistance, this 17-tooth 0.8 module pinion delivers maximum low-end torque — perfect for crawlers, ledge climbers, and any application where slow-speed grunt matters most.
For rock crawlers and trail trucks, a low-tooth-count pinion like the 17T is one of the most effective ways to dial in slow, controlled crawling speeds.
Key Features
- CNC-machined hardened steel
- Nitrided surface finish
- 0.8 module (32-pitch) tooth profile
- 17 tooth count for maximum torque
- 5mm bore for standard motor shafts
Performance Benefits
- Maximum low-end torque for crawling and climbing
- Slow, controlled crawling speeds
- Long service life under high-torque applications
- Excellent wear resistance from nitrided steel
Usage Notes
Apply removable (blue) thread-locker to the included M4 x 4mm setscrew. Use a 2mm hex wrench for installation. Pair with 32-pitch spur gear and 5mm-shaft motor.
