They are full wheel spacers
I have different ones on my Kazuma 50.

They are individual wheel spacers that add 1.5" per side for a 3" wider stance. I originally had a full set on front and back wheels but I found that the front one interfered too much with the steering so I removed them. The atv is much more stable with just the back ones
