32P Hardened Pinion Gear Set 1/8 inch Hole 17T 18T 19T 20T 21T with Hex Key (Compatible with 0.8 Metric Pitch)

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.

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

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.

Works good

The gears were exactly what I needed and best of all I didn’t have to wait.

Thue look very durabale, Great product great seller, fast delivery

These are probably the quietest 32P gears I've heard in a long time on an rc vehicle. Installed the 19T (not pictured) on Tamiya Rookie Rabbit (DT-01 chassis) with OEM Johnson 550 motor. Came in an anti-static bag in a small box. Included the Allen wrench and 9 extra set screws. Heavy, hardened steel. Lazer etched with pitch and tooth count. Considerably wider gear hob and overall length but, working perfectly. Just double check your clearances to ensure proper mesh and fitment (you may even have to install the pinion backwards depending on your vehicle). Added some size comparison pics using the 17T for example.

Good product but they’re a bit big for the traxxas rustler vxl.

Item as described

Bon produit!

They are strong and good for the price I needed these because I didn't know what gearing to use to keep the car fast but not overheat

Good quality gears fit in my trx4 fine

Overall good quality on the metalwork however compared to some other pinion gears I have used in my Slash 4x4 they are taller and don’t allow me to have it far enough on the motor’s output shaft but it is also too large for me to use it the other way around on the shaft. Making the area that the grub screw is screwed into smaller would be ideal. Also I think it’s worth mentioning that I received a few extra grub screws.
