I tried a 28T pinion on my 13.5 T motor for my stadium truck. A regular steel pinion wouldn't fit due to a short motor shaft. These work fantastic! I haven't had any problems with a 13.5T motor. I will definitely buy more of these.
*WARNING* the set screw on these pinions are 1.3mm, not 1.5mm!
Love these pinions! Running them on my B6 w/ a 13.5T. I wouldn't go lower than that. Also, I used a fine tip sharpie to write the number on the metal of the pinion. It would be nice if they had it stamped, but we adapt.
I did also have trouble like the guy who gave one star. My 29 tooth came unfastened after one run and became attached to the motor and kept working. It took a lot of work to free it without doing any damage to the motor or pinion. Still love them, they just need some QC.
Amazing pinions. I use it in 17.5 2wd buggy and 13.5 4wd buggy racing.
These are very good and did not strip out even on high traction off road carpet racing
Great pinions! Have not had any issues so far with them. Lighter than any other pinion you can find. Perfect for 17.5 racing. Would not use for mod racing.
Works great on my B6.1 17.5 wheeler. Light weight and quieter running gear train.
Just a tip, I have only metric tools - and you`ll need a .050" hex driver for the set screw.
Very good pinions. I was worried about the durability/reliability issue because they are "plastic" but i haven't had a single one strip or chip teeth yet. I have been using these pinions for about 3 months with no issues. The only thing that came up was a difficulty in removing the pinion from the motor. I had to use a 90 degree pick to remove it. Other than that, I love these things. The price is great as well at 4.99/ea.
Pinions seems solid to me. Haven't had any issues with them in my 17.5 t5m. Exotek just released an ultra light pinion design that looks really cool. I thought about trying it in a size that I don't have, but they weigh in around 1.1g. With that being said, 175rc is still the lightest pinion available and half the money, so I'm sticking with them. It makes the most sense.
Simply Amazing !!! Color Coded for quick tooth recognition..Very Smooth.
Awesome product! So far put in around 500 laps with this in my RC10B6.1d in an indoor clay track. It makes your drive train super quiet! and quiet means efficient. I'll probably order a few more with more teeth once I get more consistent lap times to get more speed down the straightaways.
Works great on my 17.5 stock b6.4 on carpet and dirt (using a slipper, no esc timing)
I was given one of these 31T pinion gear, I too have succumb to the mysterious missing set screw.. It's out there some where.
It seems to have come out and the burr that gets pushed out the shaft side seemed to have done a couple things.. it wedged it's self stuck to the shaft and it seems to have quieted down. I had bought a backup stock gear just incase. So far it's been hanging in there for a really real long time at least 6-10 events plus practice days. I figure when it's toast I'll have to use vise grips on the end of the shaft and twist it backwards toward the flat.
great product imho. quiet, lightweight,tough. 2 big thumbs up
Lightweight, super quiet and conveniently color coded. They work wonderfully on milder turn count motors.
Super lightweight vs all metal pinions. I've been working at changing over all my 48p vehicles to these, as they are noticeably lighter and are way quieter vs a metal pinion.

These come color-coded to indicate tooth count. Should be stamped with tooth count too.
For the 31 tooth version.
The pinion is very light in weight. Problem is I may have got a faulty pinion. After one practice section the pinion set screw flew out and the pinion was stuck to the motor some how. The set screw was completely secured prior to practice. Wont buy again
