5pcs M0.8 32P Steel RC Car Pinion Gear Set | 1/10 Scale

5-Piece Hardened Steel M0.8 Motor Pinion Gear Set for 1/10 RC Model Cars

Upgrade your 1/10 scale RC car's drivetrain with this precision-engineered set of 5 hardened carbon steel pinion gears. Manufactured to a 0.8 modulus (32P) standard, these cylindrical spur gears are precision cast for tight tolerances and smooth, efficient power transfer from motor to drivetrain. Whether you're racing on a track or bashing in the backyard, these gears deliver consistent performance and durability.

Key Features

• Material: Hardened carbon steel — built tough for extended wear and high-torque applications
• Specification: M0.8 / 32P modulus, 3.175mm (1/8") bore with included 5mm-to-3.175mm adapter shaft
• Tooth Options: Available in 10T, 11T, 13T, 15T, 17T, 18T, 20T, 22T, and 24T configurations (full range 11T–35T)
• Shape: Standard cylindrical spur gear profile for consistent, low-vibration mesh
• Compatibility: Fits both 5mm and 3.175mm motor shafts — perfect for a wide range of 1/10 scale RC brushed and brushless motors
• Pack Contents: 5 × steel pinion gear + 5mm-to-3.175mm rotating shaft adapter + set screw (grub screw)
• Processing: Precision casting for accurate tooth geometry every time

What's in the Box

• 5 × M0.8 32P hardened steel pinion gear (tooth count per selection)
• 5mm → 3.175mm motor shaft adapter
• Grub / set screw

Specifications

Note: Gears with 11T–14T tooth counts are very small in size and do not have tooth-count markings stamped on them. The tooth count is, however, correct as per your order selection.

Frequently Asked Questions

Q: What motor shaft sizes are compatible with these M0.8 pinion gears?

A: Each gear set includes both a steel pinion gear with a 3.175mm (1/8") bore AND a 5mm-to-3.175mm rotating shaft adapter, making these pinion gears compatible with both 5mm and 3.175mm motor shafts — covering the vast majority of 1/10 scale RC car brushed and brushless motors.

Q: Are these gears compatible with 32P spur gears used in 1/10 RC cars?

A: Yes. M0.8 and 32P are equivalent gear pitch standards (M0.8 ≈ 32 pitch), so these hardened steel pinion gears mesh correctly with standard M0.8 / 32P spur gears commonly used in 1/10 scale RC touring cars, buggies, and drift cars.

Q: Why don't the 11T–14T gears have markings on them?

A: Due to their very small physical size, there is not enough surface area on 11T–14T gears to stamp tooth-count markings. Rest assured the gear tooth count is correct as specified in your order. If in doubt, count the teeth — they will match your selected tooth count exactly.

Q: What is included in each pack of 5?

A: Each pack includes 5 hardened steel pinion gears of your chosen tooth count, one 5mm-to-3.175mm motor shaft adapter, and a grub screw (set screw) for securing the gear to the motor shaft.
