Pay attention to polarity
They work very well and way more power than original motors . The only drawback is you have to figure out the polarity from left to right motors to synchronize direction.

Check your RPM
Perfect fit for the CAR rock truck obviously I just got them and installed them so no idea on the longevity!! I’ll probably have to change the motor back to the 11000 because the 40000 is way too fast, but it was one of the only ones that gave the proper measurements. I think the 11000 rpm is an odd rpm for these ride on’s, because of the small tires! I chose to solder the connections because the factory plugs were different! Anyway know that the rpm on this motor is FAST!!

Doesn’t work.
As soon as I got them installed I noticed that it only goes in reverse, will not go forwards at all, so I wasted time and money and will be having to put the originals back on.

Endless fun
Upgraded the kids powerwheel from a single motor to double. The kids are now able to drive on the grass in the safety of the backyard. Seems durable so far as we have many hours on them already.

Wouldn't recommend product due to longevity or lack thereof
Motor burned out after about an hour of use. A little sad it's the first time using it after buying it that it died and let the smoke out of one of the two motors meaning the windings toast.....
