2PCS Kids Ride On Car Gearbox 12V RS550 40000RPM High-Speed Motor Gearbox for Power Wheels Kid's Ride on Toys Upgrade,High Torque Motor for Kid's Electric Vehicle Replace Parts,2 Free Coupler

Works well

Purchased these 11 days ago. Had them installed for about a week. My son had maybe two hours total worth of drive time with them and it seems either the motors are shot or the gear boxes are shot. Was nice while it ran. The motors are both hot to the touch, smell of melted plastic and tires no longer spin and the hub no longer spins. Not happy with this purchase at all. Wouldn't recommend.

very good

Very good quality and easy to install to replace old units on power wheels.

Good 👍

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!!

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.

Cheap power wheels upgrade and super easy to install. Hold on, this will turn that power wheel into a rocket, especially with a a Milwaukee 18v conversion

They fit perfect and for the price can’t go wrong

I recently snagged a pair of RS550 motors for a little winter project I’ve got going on. I’m upgrading my kids’ 12V 4x4 ride-on to pump some adrenaline into it for spring. I haven’t been able to take it out for a proper trail run yet, too much snow out there! But I’ve got everything installed and did a little bench test, and let me tell you, the difference is pretty wild. The Good Stuff: First off, the speed? It’s going to be insane! These motors are rated for a whopping 40,000 RPM, which is a huge upgrade compared to the stock ones, which usually sit around 10-15k. Just spinning the wheels in the garage, you can feel the extra torque and speed. It’s like night and day. Installation was a breeze, too. They fit right into the existing gearbox housing for standard 12V ride-ons, no fuss at all, just a direct swap. Oh, and I really liked that they included two free couplers. That was a nice touch! I didn’t have to scramble for adapters or try to make the old, worn-out ones work again. These feel solid and hefty, definitely not like those flimsy toy motors you often see. The "Heads Up" Stuff: Now, here’s a little heads-up: this isn’t exactly “plug and play” for everyone. You’ll probably need to know a bit about wiring or soldering to get the connectors to fit your specific ride. And honestly, 40,000 RPM is no joke. I’m kind of worried these might eventually strip the plastic gears on the wheels with all that power, so I’m planning to be gentle on the throttle at first. Bottom Line: If you’re looking to give some fresh life to an old Power Wheels or want to make sure your kid is the speed demon on the block, these motors are a great, budget-friendly upgrade. Just be sure you’ve got some DIY skills to get them in there right!

These are fairly decent. They've got a decent amount of power/torque. There's an included attachment that connects the gearbox output to whatever you bolt the attachment to, which makes it a good amount more versatile if you're repurposing it for a project. The plastic enclosures seem sufficient, but they aren't really heavy duty. I'm using them as crank power generators and they work very nicely. Of course voltage varies how fast you crank, but they've been solid in my test setups. For the 40,000rpm claim, I couldn't get them running that fast (when running off 12V, not in the crank scenario), so that might be a bit optimistic.

Unbelievable powerful
