I've bought these before and had good luck with them. I'm struggling to find the link for the other type I've bought, but they were on Amazon and didn't say RZR, just blank.
2017+ RZR XP, RZR XP 1000, RZR XP4, RZR XP4 1000, RZR XP TURBO, RZR XP4 TURBO, RZR RS1. Replace Part Numbers.

These look like the other ones. Can't go wrong with any of them really, all the same Chinese junk and you're just gonna bash em into rocks and break em again anyway lol.
