I have a standard 2013 Polaris Ranger 800. We use it for duck hunting primarily in flooded rice fields (about knee deep--sometimes more) water. But I also use it for other things. Hunt with a bunch of guys who also have them--many have done mods and lived to regret it. The big thing seems to be adding larger tires and or lifting the machine. I personally added tires that were 2" more in diameter but the same width as the original tire and changed to an aluminum rim. The repair guy at my dealership told me he repairs lots of problems created by heavily modded suspensions and that I should keep my changes to about what I did and won't see any issues. But the guys who have trouble are the ones that add big tires and change the geometry and therefore the torque angles of the suspension. Those guy snap front axles all the time. I see it all the time. Keep in mind we are using our machines in flooded fields...muck and mud under water almost all the time. So what you see on dry land might be different. We also tend to load the things up with dogs, guns, decoys, bags, 4 people etc...and of course when we do that its not like we drive around at 40 mph either. If we go more than 10 mph it would surprise me. I do have a friend who bought a Razr last year to use duck hunting and he is very disappointed in the thing. Its not geared correctly for the kind of work we do with our machines and really struggles to keep up with the other more generic machines in several ways. I'm sure it would smoke everyone on a dry trail with two people in it. But that's not how we use em.... These things aren't cheap to maintain. I broke a cooling fan blade in mine this year and the bill was $600 parts and labor... This seems to be a common problem with these machines. You literally had to disassemble the whole front end to get the clearance you need to access the radiator/fan assembly. I would have done it myself but I didn't have the time or part on hand and it was the middle of the season and needed the thing back in service the following weekend. In contrast I put a cooling fan assembly in a Nissan Maxima last year---the part was $129 and the job took me 15 minutes. The Polaris part retails for $289! Though you can find it cheaper if you look around.
