    • Soft start and faster!
Works pretty good. Does require some knowledge to install. Most of the reviews talking about it not working are inexperienced when it come to wiring and modifying power wheels. Just watch a youtube video about it. Has a built in cooling fan and the speed modes are awesome. Speed 3 increased the stock truck speed by 1.5 mph. About 15% in my case. And it has soft start so no whipping my sons head around. Which is something every stock power wheels does and my kid hates it. So double bonus. ... show more

    • I Do Advise
Honestly I was skeptical at first- I am no stranger to wiring in any capacity but I bought it because I know I could fix or modify anything shoddy on it - but to my surprise - this kit is pretty perfect. Perfect lengths of wires/plugs. Great price point -strong for my more custom than the average builder build would be. Anyone could install this kit, or replace a worn out kit with ease. If I could give it 10 stars- I probably would. ... show more

    • Must have for upgrading
This harness worked great for what I needed. I have used two so far to completely rebuild my kids toys. Combine these with upgraded motors, batteries and you got another couple years of life out of the slow power wheels. Some parts may need a little modification to fit but thats what you should expect. Anyone can install this. Wire lengths have been perfect. ... show more

    • Poor Quality
Kit was awful, wired everything up and only reverse drive switch worked. Poor soldering.

    • OK enough….but
The kit arrived quickly and the install was pretty straight forward. The speed on 24v over the 12v is impressive. My kids actually want to drive this car now. Only down side is that the “on” button or power button lit up 2 times before it quit. Now my kids cannot tell if it’s on or not. Defiantly thought it would last longer than 2 times. But the button still functions. Good product but could be better. ... show more

    • Works as intended
I have bought several of these for various ride on toys. They were pretty good definitely an upgrade from most stock versions.

Review Image by CabbyFam
This is great, I used it to upgrade my daughter's jeep from 12v to 24v with upgraded motors. Everything truly is plug and play but I ran into issues with trying to replace the old components like the buttons for power, speed, pedal, forward/reverse, etc. I needed to remove the cables from them to plug them in and then reattach the cables, but it's literally impossible to remove these cables without breaking them. This made the process a whole lot harder and time consuming than it needed to be. Also, the power button was lighting red initially but then quickly stopped lighting up for some reason. Even though it still works, my kids just can't tell when it's on. I didn't give it 5 stars because of those 2 reasons. ... show more

    • Don’t let your lack of knowledge stop you from trying
My son wanted to upgrade his 6v corvette to 24v… my response was, say less son! & here I am ordering new motors and cords based off the previous sketchy reviews on this product. Let’s take a chance My final notes: 1. It really is plug and play. Easy assembly. Take pictures before you undo the cords and try to install new buttons and foot pedals. 2. The plugs are loose fitting… tighten everything. 3. The power button light does not work after three uses. So hopefully you have dashboard lights to use as reference that the power is on. 4. Use the reference video in the product description to help you figure out what could be the problem. Overall: it works and works well for the price too. I suggest you just change everything. Cords, motors.. all of it. ... show more
