Issues with Axys aluminum a-arms

Does anybody know if the. 15 pro arms will fit and work fine cus I have a 15 and if I'm out west I know I'm going to want to ride my sks vs my 15 from all the great reviews if I were to bend a arm

They do, but you'll need to thin out the plastic bushings for them to fit, as the bulkhead spacing and pocket width was changed slightly.

I have not done this swap but that is what has been posted in other threads. FWIW
 
Thanks for calling me out on this. I hate it when guys post general statements with nothing to back it up, and I went and did just that.

The top arms are well built. Nothing wrong with those. But, for the lowers, it looks like they tried to build a fail point in right where you're seeing them bend on previous pics. At that location, there's just a thin section of aluminum. Right where the brundt of a force happens, especially when a ski is turned. That's quite a load on just a thin piece of aluminum. If they would have at least made an 'I' beam or 'T' there, it would probably be fine. A tubular structure, like the old arms, would be significantly stronger. Maybe they did their initial testing out of some premium billet and are now sweating it with these forged arms? Seems maybe the design was based upon a forged control arm of a car, which doesn't see nearly the side loads that a snowmobile arm sees? I don't know, but I wouldn't doubt it if there's a bit of scrambling going on about this over at Polaris at the moment.

Easiest fix would be to go aftermarket, but maybe you could tie into the rear mount with a rod and connect to the sway bar mount? Somebody will probably come up with something.

I didn't mean to sound like i was calling you out. I just like to gain some knowledge from those who know and understand these things. I wonder how long before someone fabricates a little "collar", to go over the stock arm in this location, or a "T" like you suggested, that clamps around the arm to give that area a bit more strength. Seems like, with the right tools, it should be relatively easy to do . . .? In looking at mine, that does indeed look like the weakest area on the a-arms.

I was thinking exactly the same thing.
I could whip something up on my 3d printer but not sure if a piece of abs would be strong enough.
Besides I would much rather been an arm than screw up the bulkhead.

With that said, I was pretty rough on the thing last ride and had no issues. May just be a fluke and hitting something at just the right angle to send all the impact force to the weak spot.

Selling my zbroz 39" if anyone is interested.

How many of you remember the Polaris sleds with trailing arms? The stock ones bent and they were really heavy too. I ran Holz trailing arms and they were real light and they also bent if you hit something. I will run the stock a arms until I bend one. My suspicion is that Polaris will do something about this if it is as big a problem as the suspect driveshafts on the 13s. It would be nice to know how many riders have suffered bent a arms so far. Nevertheless, riding this time of year is tough on equipment. Last year's thin snow left its mark on lots of sleds too. I saw two in the parking lot on New Year's Day that had about $3,000 front end damage. The carnage occurred within 100' of the two riders. Rocks, stumps, etc. are going to cause damage regardless of how strong the a arms are.

Just want to go narrower. Smaller arms, smaller target.
 
carbides?

Does anybody know why manufacturers are still putting carbides on mountain sleds? On the Assault, sure ok maybe, but on the standard pro-rmk, it sounds like I'm in about a 75% majority of people who never wanted that carbide on there in the first place - give me a wear rod, and I'm good, and while you're at it Polaris, take the $20 of the MSRP as well. Every little bit helps.
 
Because we ride a lot in michigan I have been running 6 inch stud boy shaoer bars and never had an issue bending one. I broke a couple of a arms before butbthat eas my fault.
 
Axys aluminum a-arms

Wow John! Maybe it time for matching Zbroz spindles :). Did it take a hard hit to do that?


I hit the side of the ski on a tree. I suspect with the taller spindle and thinner material it was just too much. This sled rips (300 miles now) but definitely has front end durability issues.

looking at mine for a while yesterday i think im going to leave it as is and see if I have issues, the problem I see in making them stronger with a billet brace is how much will the mounting take? looking inside, yes I could make a nice support for the arm mounts running side to side across the bulkhead, but question is where do you stop? i'd have braces running all over the place lmao, cause the upper arm would probably break off if the lower held firm, ect ect ect :face-icon-small-con:face-icon-small-con
 
I just got a set of KMOD's off the UPS truck... The build quality on these is great... These are for a ProRide... but I've seen the AXYS... only minute differences for fit.

Buddy smoked a stump today coming down a nasty draw. Hit HARD, flew over the bars, stopped the sled in its tracks. All stock.......ZERO damage. Thought for sure it was gonna be bad news. Eric


Musta had a bunch of little angles holding the A arm together!!!
