Overview
The Hot Racing Steel 34T Mod 1 Pinion Gear is a hardened-steel pinion designed for 1/8 scale brushless RC vehicles, including the Arrma Limitless and Infraction. CNC-machined from hardened steel and finished in clean black, this 34-tooth Mod 1 pinion delivers a balance of top-end speed and acceleration for high-power 1/8 platforms.
One tooth less than the 35T option, the 34T pinion offers slightly more acceleration and slightly less top-end — a useful tuning option for drivers fine-tuning their gearing for specific track conditions or driving styles.
Key Features
- CNC-machined hardened steel construction
- Black finish
- 1.0 module (Mod 1) pitch
- 34 tooth count
- 5mm bore for standard 1/8 brushless motor shafts
Performance Benefits
- Balanced gearing — more acceleration than the 35T, less than the 33T
- Hardened steel handles brushless torque
- Long service life under high-RPM operation
- Consistent gear mesh quality
Usage Notes
Apply medium thread-locker to the pinion set screw. Verify gear mesh after installation. Confirm correct spur gear pairing. Monitor motor and ESC temperatures when running high-speed gearing.
