RRP8622 Extra Hard 5mm 22T 32P Pinion

Robinson Racing Extra Hard Blackened Steel 32 Pitch Pinion Gear – 5mm Bore

Built for durability and performance, Robinson Racing’s Extra Hard 32 Pitch Pinion Gears are precision-machined from high carbon steel and heat-treated for exceptional surface hardness. This makes them ideal for demanding applications—especially when paired with metal spur gears.

High carbon steel offers natural lubricity and reduced adhesion compared to softer steel grades, ensuring smoother operation and longer gear life. These pinions are perfect for motors with a 5mm shaft, including models from Traxxas, Team Associated, and HPI. If you're running a standard 1/8" shaft motor, a 5mm to 1/8" reducer sleeve (RRP1200) is required.

Available in a range of tooth counts to help you fine-tune your gearing setup. Simply select your preferred size from the drop-down menu.

Key Features:

• Constructed from extra-hard, heat-treated high carbon steel

• Optimized for use with Robinson Racing GEN3 steel slipper units

• 5mm bore fits most 5mm shaft motors

• Compatible with 32 pitch and .8 module spur gears

• Multiple tooth counts available

Note:

• A reducer sleeve (RRP1200) is required for use with 1/8" shaft motors.

• 32 pitch and 0.8 module gears can be used interchangeably with no performance loss. The size difference per tooth is minimal (~0.00027").
