## Description

Are you looking for universal spares pinion gear for your RC car? We can help, we provide 1/8 inch hole 32p pinion gear set comes with set grub screws, they work well and have a secure fit with no modification needs. Package include: 1 X 32p 1/8inch 17T pinion gear 1 X 32p 1/8inch 18T pinion gear 1 X 32p 1/8inch 19T pinion gear 1 X 32p 1/8inch 20T pinion gear 1 X 32p 1/8inch 21T pinion gear 5 X Grub Screws 1 X Hex Key 💡 Make sure you thread lock the grub screw. They are hard to find when they fall out. 💡 Larger gears will result in higher speeds while smaller gears provide more torque.  For quicker acceleration go for a smaller pinion gear (with fewer teeth) and larger spur gear (with more teeth). 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.  💡How to install the pinion gear: 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.  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.  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... Let us make your RC happier! LOL

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Grasshopper 380 to 540, finally.
  

*by M***3 on Reviewed in the United States on January 25, 2024*

I just built a Grasshopper ~38 years between my 1st and this one. Instantly upgraded to a 540 sport tuned and had to order an 18T pinion. Not realizing 2 different shaft sizes (that's what she said) I ordered the 5mm and it didn't fit. This came today and fit perfectly. It gives you a few gears to choose from and extra grub screws to spare. Great purchase.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    So far so good
  

*by T***S on Reviewed in the United States on April 3, 2024*

I haven't gotten to use them yet, but honestly they feel higher quality than my Factory pinion.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Doesn't fit arrma 6s
  

*by T***R on Reviewed in the United States on August 20, 2024*

I'm not sure honestly on how well they hold up because I bought it for my fireteam but I didn't double check on the size of the bored hole size is smaller, but it looks like it is well made and will do the job for a RC that has a 3mm motor shaft.
