2019 850 2.6 155" Hifax Part Number???

Polaris lists multiple part numbers on their website.... both stating 3" in the description. Who can tell me what the accurate part number is for the stock black light weight hifax that comes on the 155 2.6 850? I damaged one side and the other side has no wear yet so I am only looking to replace one side... So I want to make sure I order a matching part.

Thanks!
