Razor x wheels gear kit

Hi guys,

I’m looking to do my first build by modifying my Razor x electric skateboard. I love the ride on this thing but its just too slow for me. I feel like I have all of the parts down except for the gear and pully kit. Does anyone know which kit would fit these wheels?

Any help would be greatly appreciated:)

Thanks to a67676767 for the pictures.

Maybe kegel core would fit in those circular slots but that a an odd wheel. It’s a razor wheel then right?
