Review on Optimized ATV Winch Mount: Extreme Max 5600.3169 for Polaris RZR 570/800 by Jeffrey Gallagher

These will not fit even though they should be rated for the RZR570. I ended up having to turn the front brackets upside down and modify them with my grinder to make everything fit. If you look at Polaris brackets and compare them to these you will see what I mean (Polaris brackets are already reversed and properly notched).
