I've used a few of these pinions in various brushless vehicles over the years. Perfect strength and fitment.

These are the only pinion gears I use. I have been the RRP route along with countless others but none are as good as RCM. Perfect mesh and well machined who could ask for more. Like many of the other products from RCM the price just cannot be beat either.

I have been running with pinions from Monster Mike for more than a year on monster trucks running on 6S. Other pinions from other companies couldn't handle MTs on 6S but none of the pinions from RC Monster ever failed. Fantastic product Mike. Thanks.

I've purchased 3 or 4 of these over the years, and all of them are still in mint condition after use in a heavy GorillaMaxx geared for ~40mph, these will out last most trucks & are a good investment.
