Are you looking for universal spares pinion gear for your 1/10 scale RC car?
We provide 32P 1/8inch 12T 13T 14T 15T 16T pinion gear set comes with set grub screws,they are:
1.Work smoothly, the gears are milled by precisely Tanwai milling machine, good machining made them roll smoothly.
2.Durable: Made of aluminum 7075 material, Hard anodic oxidation and anti-rust treatment on gear surface,
long service life for these motor pinion pear.
3.Making you have more choice.

How to install the pinion gear:

1. You will probably need to loosen the motor a bit, in order to fit the pinion gear on. Make sure you lock it in place on the flat portion of the motor shaft.
2. When you are tightening it back up, make sure you leave about a gap between the pinion gear and the spur gear.
That gap will be very small. It should be about the thickness of a piece of paper.
3. At last, if the motor you are using has a 1/8 inch shaft with an 32p spur gear then it should fit... It's not about what vehicle you have necessarily
4. Please make sure your spur gear and pinion gear have the same pitch, or the teeth won't mesh.
Notice:
1. For quicker acceleration go for a smaller pinion gear (with fewer teeth) and larger spur gear (with more teeth).
2. Your car will accelerate off the mark very quickly with more torque, and you'll also benefit from cooler
running temperatures, extending the life of your motor and ESC.
