HOPLEX 32P Hardened Steel Pinion Gear Set 14T 16T 18T 20T with 3.175mm Coupler for RC
HOPLEX 32P Hardened Steel Pinion Gear Set 14T 16T 18T 20T with 3.175mm Coupler for RC
This HOPLEX pinion gear set provides four hardened steel pinions with 14, 16, 18, and 20 teeth, all with a 32-pitch and 5mm bore. A 3.175mm coupler is included to adapt these pinions for motors with 3.175mm shafts. Each pinion features an M4 set screw to secure it to the shaft. This set is suitable for RC buggies and monster trucks that use 5mm or 3.175mm motor shafts.
What motor shaft sizes are compatible?
The pinions have a 5mm inner diameter bore, designed to fit 5mm motor shafts directly. Additionally, the included coupler reduces the bore to 3.175mm, allowing use with common 3.175mm shaft motors. This makes the set versatile for different motor types.
Gear ratio flexibility with four tooth counts
The set includes four pinions with 14, 16, 18, and 20 teeth. By swapping pinions, you can change the gear ratio of your RC vehicle. A lower tooth count (14T) typically provides more acceleration, while a higher count (20T) can increase top speed. Having these options allows you to fine-tune performance based on your track or driving style.

Build quality and construction details
Each pinion is made from high-strength hardened steel for increased wear resistance. The machining process aims to reduce roughness and noise compared to some other pinions, allowing for smoother rolling. The M4 set screws help prevent slipping on the motor shaft, providing a more secure fit.
Frequently asked questions about this pinion set
What is the tooth pitch of these pinions?
The pinions have a 32 pitch (32P), a common size for many RC cars.
What is included in the package?
The package includes one 14T pinion, one 16T pinion, one 18T pinion, one 20T pinion, one 3.175mm coupler, and one allen key for the set screws.
Can these pinions be used with a 3.175mm motor shaft?
Yes, the included coupler allows the 5mm bore pinions to be used with 3.175mm shafts.
Who will find this pinion set useful?
This set is designed for RC hobbyists who own buggies or monster trucks with 5mm or 3.175mm motor shafts. It is also useful for those experimenting with different gear ratios to optimize performance. The range of tooth counts provides flexibility without buying individual pinions.
