550 30000RPM Gearbox with 12V Motor,Electric Motor with Gear Box for Kids Electric Cars and Motorcycles High Speed RS550 Drive Engine Match Children's Ride on Cars

Works perfect for four wheeler. My son loves the speed. It gets pretty hot fast but hasn’t quit.

Product arrived quickly, like before 9am which was huge as that aloud me to begin/finish my project. I bought 2 of these to replace the ones that came on my sons “kidzone Jeep”. The stock ones were 10000rpm so figured this would be a good upgrade. His stock ones broke within 3 months so these were needed either way. These came pre-greased but I threw more lube on anyway. Super easy install had the jeep up and running in minutes.

We have had my sons best choice jeep for 18 months and one of the motors internal gears wore out so I ordered 2 of these I figured I may as well replace both. As soon as we installed these they where noisy and one stopped working immediately. I reinstalled the good original motor and the jeep worked fine although noisy for about a half hour until the other one broke. Now he is using just the one original motor.

I shattered the gears on the original gearbox for a Big Toys Green Country Tundra ride-on truck. The provided measurements in the product photo were slightly different than my shattered one I had but it looked the same so I ordered two to have a matching pair (left and right). As it turns out, the measurements being close was good enough. The gear does have metal teeth as shown in the product photos. The motor is stamped with a 12v 30000rpm rating. Took the connectors from the Tundra and attached them to the new gearbox without any issue. It does draw a ton of amps and after one minute of runtime, it does pop the stock onboard breaker (I'm replacing it with an inline 30A Automatic Reset Relay Fuse) to handle the pull.Overall very pleased with the gearbox.

Fit perfectly in my SL AMG Mercedes. I did have to reconnect the old wires from old motor because it came with opposite connectors. Motor is a lot faster than stock. It does cut out but I have to upgrade my automatic reset fuse. Motors run great.

Ordered this for replacement on my kids power wheels car. Noticeably slower than what they had before. Even they complained about that. Too bad...

Bought a pair of these. Two gearboxes pull 15 amps combined on a paved flat surface. When in the grass, current spikes to 35 amps. That's high current! Make sure the wiring can handle it that. Also the car needs a large battery that can supply that amount of current for any reasonable amount of time.Now the car is almost too fast to run after. Not for a beginner driver!

I upgraded the battery on my kids 4-wheeler, and promptly stripped the gears. This solved that problem, but they are still afraid of it.
