If you are looking to make your kid's power wheels go faster this is the motor for you!

These are easy to replace, please note you will need to buy a pinion (gear) that matches your existing motor (32p & however many teeth ie: 16, 19, 21etc)

replacing the motor just involves cutting the wires off the old one soldering or using a connectors to hook up these putting the pinions on and then mount them onto the gearbox with two screws.

You MUST replace both motors if you upgrade to this.

Want to go really fast? convert your 12v vehicle to 18v its easy to do and the kids have a blast.

Only 4 caveats I will give. 1. never go to 24v. The factory wiring (14awg) will not hold up to 24v nor will ANY motor. Secondly make sure that the pinion lines up with the first gear in the gearbox or it will chew it up and render it worthless. 3rd since you have the rear wheels off to remove the gearbox take the gearbox apart as its only has 4 screws and 4 plastic gears in there and LUBRICATE IT. Clean it all out and put grease everywhere bearing grease works great. Lastly go to Ace hardware and get some 7/16" shaft collers to hold the wheels on they are a million times better then the cheap plastic cap nuts that fisher price provides

Used a pair of these to replace the motors in my kids little tikes h2 hummer, one of the original motors had blown due to over voltage. At 12v these were visibly faster than the original motors at 12v. At 18v these motors were visibly faster than the original motors at 24v. Money well spent! Just make sure to get a 32P and same number of teeth pinion gear and your on the way! My kids love how fast there h2 hummer goes now and I can hold off investing in a go cart for a little longer.

Using these in my son's Monster Traction PowerWheels F150. Replaced along with the 32P 16T pinion gears necessary to work with the PW gearboxes. The truck clearly has more power and speed on hard ground, but for the back yard the performance and runtime is severely diminished. I may try increasing the voltage and upgrading all the wiring, but will probably end up going to a different motor with more torque if that doesn't help.

For somebody with a road-going PW and minimal grass or hill usage, these would be a great upgrade for kids craving more speed.

Bought this to upgrade my son's power wheels 4 wheeler. This sure makes the unit faster, but drains the battery quickly. I would recommend a set of these as long as you purchase an extra battery with them.

We bought this engine to replace the factory Traxxas Titan 12T in a Traxxas 1/10 slash model. It seems like a well made engine, however the speed was 50% slower than the stock Traxxas Titan 12T engine. We were using a LiPO 25C 2S 5000mAh 7.4 battery. From some of the reviews, we thought we could just pop this engine in and get good performance, however it appears as if you need a different battery (more voltage?) to get high performance from this engine. We are new at RC, so please comment if you can help us out. Thanks.

Made our power wheels Super fast. We added a 2nd 12 volt battery in series and Oh my god its FAST! If you go 24 volts be sure to add cooling fans. They have held up very well for 2 months now. Excellent!

UPDATE: Over a year now and still running strong. Burned off 2 sets of tire treads! I recommend only adding an extra 6 volt battery (18 total) as a 24 volt system is probably a little too much! speed. These motors rock!!

Put these in my daughter's off-brand powerwheel. Low gear is now as fast as high gear was, and high gear is almost too quick. After a half hour of hard use I felt the motors, and they were only a little warm. Awesome! we'll see how long they last. If they make it through the summer, I'll be buying again!
