YijiaLink 5-Pack 32P 5mm Pinion Gear Set 13T-17T for 1/8 1/10 RC Cars
YijiaLink 5-Pack 32P 5mm Pinion Gear Set 13T-17T for 1/8 1/10 RC Cars
This YijiaLink 5-pack delivers five 32-pitch steel pinion gears with tooth counts ranging from 13 to 17, each featuring a 5mm bore. Designed for 1/8 and 1/10 scale RC cars, trucks, and buggies, these gears fit motors with 5mm shafts and are constructed from hardened steel for repeated use. Whether swapping ratios for speed or torque, this set covers common options.
What's in the pack?
- One 13-tooth pinion gear (5mm bore, 32 pitch)
- One 14-tooth pinion gear (5mm bore, 32 pitch)
- One 15-tooth pinion gear (5mm bore, 32 pitch)
- One 16-tooth pinion gear (5mm bore, 32 pitch)
- One 17-tooth pinion gear (5mm bore, 32 pitch)

Compatibility and fitment
These pinions work with 1/8 and 1/10 scale RC models that use a 5mm motor shaft. Compatibility includes many Arrma, Traxxas, Axial, HSP, Redcat, Losi, and similar vehicles. Before installation, confirm that both the motor shaft diameter and the gear pitch match your spur gear to avoid poor meshing or damage.
Does the pitch need to match the spur gear?
Yes. The pinion and spur gear must share the same pitch — in this case 32 pitch (0.8 module). Using mismatched pitches will prevent the teeth from engaging correctly and can strip gears. Always verify your spur gear's pitch before swapping.
Material and durability
Each gear is made from hardened steel, which offers good wear resistance under normal RC use. The set is designed to be reusable; you can swap ratios as needed without replacing the entire gear.
Tips for choosing the right ratio
Lower tooth counts (13T) provide higher torque but lower top speed; higher tooth counts (17T) do the opposite. Experiment with the five included sizes to find the best balance for your driving style and track conditions.
Frequently asked questions
Will these fit a 3mm or 3.17mm shaft?
No, these gears have a 5mm bore. They require a motor with a 5mm shaft diameter. Motors with smaller shafts will not fit.
Are these the same as 0.8 module gears?
32 pitch and 0.8 module are functionally equivalent and commonly used interchangeably in RC applications.
Do I need any additional tools to install these?
Standard RC tools (hex drivers, a pinion puller if needed) are required. These are direct replacements for existing 5mm pinions with the same pitch.
