This gear combination is for the hard core top speed addict only. It will fit in our Phoenix Gearboxes and in 7R Gearboxes that stock used a 15, 16, or 17 tooth pinion gear and with 775 motors. This combination changes the final drive ratio to the highest possible top speed of any ride-on today. It is for on-road use only with no passengers in the car or there may not be enough low-end power (leading to fuse blowing).

The First Gear is the weakest link in a Power Wheels 7R Gearcase. This is the solution. We designed this gear with a leading American gear manufacturing company to be so strong we offer a Lifetime Warranty* on it. The gear is made from one solid piece of stock, heat treated, and has holes to cut weight. The steel ball bearings reduce friction, heat, and resistance making for the most efficient gear possible.

To install this gear in a 7R gearbox you will have to sand the black finish off of the shaft that it spins on. Do not sand the black finish off of the portion of the shaft that installs into the gearbox housing. Clean the grease off the first gear shaft, then mark the base of the first gear shaft. Pull it out and put the portion of the shaft that was stuck in the gearbox into a drill. Spin the shaft on 120ish sandpaper, stopping every few seconds to test fit a bearing. The bearing must slide smoothly all the way to the mark you made. In a Phoenix gearbox you just put it in.

When using 775 motors you must use the 775 To 7R & Phoenix Mounting Kit linked on this page.
Will NOT work with stock Power Wheels motors... it will tear up their pinion gears.

If you are replacing a stripped nylon first gear you will need to replace the grease too as it is contaminated with plastic fragments.

*See our Warranty page for details.

1 of 5 Save your $$$$ October 11, 2021
Reviewer: Mike G from Oakley, CA United States  
I finally caved and decided to buy this stage 5 kit for highest possible gear ratio and max speed. Well I previously already had the standard steel firsts installed in 23t gearbox with 775 motors. I have various other custom mods Ive personally created and done to my vehicle like adding bearings to the 2nd and 3rd gears. With a cheap esc on my original gears at 30v my son topped out at 16mph in his Porsche gt3. So upon installing (which I couldntt do right away because they forgot to send me my pinion gears) I was feeling confident on hitting atleast 18mph at 30v. The way these are marketed I mean yeah! I should hit that speed. Well quite to the contrary I didnt. As a matter a fact nothing changed besides the numbers in my bank account. Still topped out at 16mph at 30v. In my opinion save yourself the money and just stick with your 23t gearboxes. Its unfortunate the monopoly on critical parts for upgrades is solely within this business as its mediocre at best. Happy modding. Peace.
