Bigger tires? Axles breaking? Warning from dealer? What should I do?

Hey everyone,
I recently was in my polaris dealer showroom and saw some sweet 29.5" Anarchy (I think) tires mounted on matte black Polaris rims, they looked so sweet, so I inquired about price and he was gonna give me a sweet deal on the set but then proceeded to ask what machine I had and then said to not even bother because I'll snap my axles???? I'm new to aftermarket atv parts and big tires and am wondering what I can (should) do before I mount big tires on my '11 Sportsman 850. What are the best aftermarket axles (for the price) and what other mods should I make. And/or is it even worth it?
I know guys who run 29.5s on stock Canams with out much issue.
Any information would be greatly appreciated. I really would like some big tires eventually but sounds like I should start somewhere else first.
The guy that I talked to at the dealership always is honest with me and always gives me deals.

You can run anything you want on stock, but eventually it will go due to rotational forces. Basically the force exerted by the larger tires will be too much for it to handle. When will it go, who knows. Tomorrow or two years is the question. Most likely when in a mud hole. For axles, Voodoo is a solid choice. Forget Gorilla, quality has gone way down (friends opinions). Not positive, but am thinking you will need a lift kit with those wheels as well.

Start with this Polaris Scrambler 850 and 1000 billet pinion cover ? HD ATV Gear
29.5s will still rub a bit even with HD springs, you will have to max your preloads for sure.
Next get some Rhino front axles from superatv($200) Usually its the fronts crapping out, If you have a heavy thumb do all 4.
Don't skimp out on a clutch kit either, call Ryan at RVSperformance.


2012 850xp eps
32" Sludgehammers -5"/2" lift -Turner eagles
MSA battles 5+2 - GSE filter - Ranger Gears
RJWC single w/QC and programmer.
HD springs -QSC clutch kit/ EPI HD belt
Heretic Lights -Front diff fix -Cecco frame braces
Jccapri bushings -Swaybar removed.

Will that pinion cover fit my 2011 850? I don't see that year listed.

Sorry you need the long cover, it removes the ADC, Solder in a resistor to keep the idiot lights off.

Those anarchy tires look interesting, like radial outlaws and reg outlaws put together.

Nope its not an issue, but its built into the cover up to the 14s i think, so swapping covers you loose it.
The stock cover is thin cast alum that snaps off a the bolts.
The replacement is milled from billet alum.
Heres a vid from a member on here with his new bike

i am running 30 inch zillas on 14 inch rims on my 2009 800 Sportsman - granted i have a Dalton clutch and a 2 inch highlifter kit. I have run about 500km n o axles issues but I think it depends on how you drive it. don't goose it at the bottom of a hill whemn pulling up if you are stuck in deep snow or a boulder or root use the winch.
