    5.0 out of 5 stars Check your RPM
    Reviewed in the United States on August 24, 2024

    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!!
