Id like to purchase a replacement/backup belt for my 15 RZR XP1K. I’ve been doing some reading on the forums here and online and wanted to clarify that this is the belt I need to purchase.

Gates 27C4159 G-Force C-12 Drive Belt for 2015 Polaris RZR 1000.

VS

Gates 21C4140 G-Force C-12 CVT Belt.

As I began reading the customer questions and answers at the bottom of the product page I’m seeing that this will also fit the 2015 RZR XP1K. My question is will both belts fit my machine and what makes the first one a more expensive/better product?

Thanks in Advance.
