Can't answer that for you but there are allot more guys viewing this forum over on the 800/900/1000 sections of the forum.

I would ask in XP1000 section.

 

I just had new PRP RZR 1000 seats installed by dealer in my 900, I can't see why 1000 seats wouldn't fit. He modded some brackets and had them installed in 2 hours.

 

yes and no.

1000/XC seats will not fit a 570/800/900 seat bracket, and vice versa. The rails are 2" further apart.

570/800/900 seats on 570/800/900 brackets will go into a 1000/XC no problem.

1000/XC seats on 1000 brackets should fit in the front of a standard 570/800/900 RZR. I've heard conflicting reports of whether or not they work in the REAR of a 4 seat 800/900 RZR.

 

Its not a direct bolt in but seen several around here with 1000 seats in 800's. The bolt patterns are different but they can be modded to fit.

 

any seat can be modded to fit if you have to tools & can do so fab work

 

That's true. The polaris dealer installed mine using a part in inventory!
