weelye WW4845 High-Power 150W Gearbox for UTV 4x4, 24v Utv Parts Motor Gearbox Children Ride on Toys Accessories,24V 3250RPM

Not sure what's in the grave digger. These are what's in the back if the torex. https://a.co/d/0eC6SYTs I don't know exactly what gearbox is in the front, but I when I looked at the front motors recently they looked like 550's and had a power rating of 30-60W -- which I found interesting; I've never seen a range. Maybe they are 12v-24v (30w at 12v, 60w at 24v? Not sure.)
