I’m stock otherwise.. am I going to have issues with axles/diffs?

I have a 2014 rzr 1000.

Or should i just stick with 29’s?

I haven’t run 32s myself, but I’ve been looking into it for a while. From what I’ve read, if you are going to run fast trails and or open desert terrain you shouldn’t have much trouble. If you run rocks, mud, technical trails you are are going to want some gear reduction. Going with a light tire will do a lot to mitigate the issues associated with the larger tires. The bigger concern over the axles and diffs will be your clutches and belt, but larger tires add stress to almost everything including brakes, steering components, driveline, suspension bushings, etc. Going to a 32” is not a huge jump and lots of people do it, but If you drive with your foot to the floor all day you’re going to break stuff.

I say get 32's and send it! But also keep the wheel bearings greased, change diff fluids more often to keep an eye on them. And a good clutch kit helps

Well, that’s your experience. I’m not gonna argue with you there. I was just stating facts: bigger, heavy tires cause more stress and increase the chance of breakage on just about everything. It will also be more demanding on the clutching system because you’ve effectively increased the final drive gear ratio. In my opinion, the factory low gear is WAY too high, so I don’t see how you could be happy with it with even bigger tires. But hey, whatever works for you. I was just trying to point out some of the potential caveats to the OP. When I go to 32s I will be doing a 33% low, 12% high and reverse reduction with HD reverse chain at the same time.

Depends if it is a true 32" tire? if it is, you can expect to roll over stuff so much easier. You get a little better approach angle with 32's, cause they stick out.
farther. I ran 32's on stock machine for 1 1/2 years, with no clutch or belt problems. But, I also always run in low since very few times on the trails do you ever exceed 25mph
Also, expect lots of rubbing without getting forward offset a arms

If you are running the stock bighorn tires that came on your machine they are not anywhere close to 29" tall they are more like 27". A true 32" tire will look huge compared to those bighorns. I have run 30" fuel grippers and they do measure a true 30" for 1k miles and have not had any problems what so ever with rubbing. I run tough technical trails and rock crawl mostly but occasionally do a fast blast down a trail or road. I have not done any clutch work yet but I do have a Dalton clutch kit with hunterworks rollers and HD belt to install this week. I think you would be fine with a true tire that measures anywhere from 30-32" with the bigger tire rubbing a little. Here are a couple pictures comparing a 28" Tensor Regulator tire to the 30" Fuel Grippers.

Larger tire is key for mountain trail riding and rock crawling. If considering 32" tires, we strongly suggest our Maximum Ground Clearance +2 Forward Arm Kit (2014-2016 models $675 / 2017-2019 models $765 *includes installed brass bushings).

Features:
- Extends wheel base forward 2" without changing steering geometry.
- Room for 32"s without fender rub with or without wheel spacers or offset wheels.
- Maximum Ground Clearance Design to crawl over those rocks and tear through those ruts that you would normally drag your OEM a-arms on.
- Built Heavy Duty with chromoly steel. #builtUSAtough
- 2014-2016 optional brass bushing kit *2017-2019 brass bushings already installed.
- Sway bar compatible.
- Can use OEM balljoints.
- Powder Coated color options for that perfect matching look.
