Get some new arms for you're 17.

They still bend very easy. Just a heads up.

I felt drunk reading that. Regardless, if you hit a rock what do you expect? The arms are supposed to give so you don't rip up the bulk head/nun.

I'm hoping that the metric units signify English is not his first language.

Regardless, I agree. Pretty sure the A-Arms were engineered to be the weak point to protect the rest of the sled.

How'd the Cat do ?

 

[Dirty Steve]

Here we go again. Yes, the stock arms are weak. Also, it's November-you play, you pay.

This hurt my head to read. Borderline hard to even decipher what was meant...

But guy hits rock, rock bends a-arms, and somehow its the Polaris a-arms fault that it bent after hitting a rock? Interesting...

Pppppuuuuurrrrrr

While this post is beyond stupid imo, I don't think it hurts to keep pounding into polaris engineers heads how terrible the stock a arms are, as they do check up on forums...

 

[Red Mtn]

The a-arms are far to weak. The engineered in fail point is a FAIL. Many have upgraded to aftermarket arms and I do not see the a-arm and bulkhead failures as some suggest. I just didn't expect a downgrade in strength from the Pro-Ride glued arms...


Ditching the carbides for wear rods seems to help.


I bent three arms last season and I am just an old man puttering around out here.

I agree... the factory arms have shown that they are not as durable as the aftermarket offerings.

And I also agree that the arms can be a lot stronger without risk to the bulkhead.
Plenty of bent or broken aftermarket without collateral damage last season.

When I get asked about this subject... I recommend owners take off their stockers while new, install aftermarket, and sell the new stockers on ebay to recoup most of the outlay on the aftermarket arms.

Which aftermarket a-arms do you recommend?

Are the braces a good option or still better off with aftermarket a-arms

That's what they said about the RZR too, feel free to check into how that worked out for those guys.

What he said ^^
I have only seen one arm bent, and that was after tagging a rock . . .hard!

 

[RMK935VA]

KMOD 37 A ARMS are what I run. I hit a solid piece of steel on top of a damn that would have destroyed the stockers. It slightly bent the lower. I rode it for three more rides before replacing it. They are strong and I like the more narrow stance, the bolt on capability, the compatibility with stock shocks and the high quality build.

 

[mountainhorse]

I've got a set of the K-mods as well... VERY high quality in the fabrication... beautiful welds...

Took my new stock arms off and sold them for $350, then i bought Alternative Impact arms for $515. Well worth the investment.

I looked at and considered all the aftermarket vendors, but ended up on Alternative Impact, because of the fact they have rod ends on their arms. The rod ends should brake before the arm on a impact, and if you have a spare rod end and some tools, they are easily replaced on the trail.

 

[Sage Crusher]

Heck I will sell my stock A arms if I could get that price for them.
They are just sitting around and thought to re-install when I trade up...

 

[Polaris RMK M.M.R.]

bought 37" k mods, took my stock arms off my 2016 at 40 miles. sold for $400 shipped and never looked back!

 

[trackvs2wheels]

For all you selling your stock arms...don't you feel horrible as a person for selling such "sub-par" items to your fellow snowmobile community????
