2021 Camso ATV T4S tracks. I bought these to use for a hunt and it's done now. They work great in the snow, I've put about 350 miles on them this winter. Front tracks have a little wear but work great. If you are putting them on another grizzly and want the brackets, I'll make you a deal on them also. Located in Afton, WY. Asking $3000 obo.
