Alternative Impact a-arms

[jbaisley]

Has anyone had a negative experience with the Alt. Impact a-arms. Do the end bend or break too easy on light impacts? When they do brake and the ski pulls out to the side does it hurt anything else? Got bent a-arms from a light impact sidehilling and trying to decide which way to go on the repair. I am planning on adding the brace kits also.

The rod ends will usually break first. They are designed to do this. On the Ski-Doo the weak link seems to be the S Mod. If you have the brace kit it helps. The Alt A Arms are awesome and hold up to abuse. I always encourage people to keep a pair of ends in their pack so if they hit something hard and something breaks, they are only a few minutes away from riding again.

I have not had any issues in the past, this is the first a-arms that it have damaged between my 06 Summit and the 14. If they broke too easy I thought the repeated twisting would end up damaging it anyway.

I've had the Alt Impacts on my XM 154 for a full season now and have sheered off one rod end and bent two others as they were designed. BUT, I've also taco'd the lower arm on each side now too. They both kinked, then snapped, right above the sway bar tab. I'm not going to run the sway bars anymore and hopefully won't have that problem and would suggest not running yours if you go this route. The GnR or Fett Bro braces are a must... but not sure I'd do the Alt Impact arms again.

I will have a set of these arms for sale at the end of the year if anyone is interested. Getting a new sled and not giving them away on trade in. PM me if interested. If you can get these arms to work as advertised they are the ticket.

A couple inches behind the sway bar tab is were the stock a-arm bent down. The impact was not even enough to knock me off of the sidehilling line. Possibly the sway bar pressure creates a stress point.

I've been through 2 sheared & one badly bent rod ends, and very happy with them. Friscoprox just likes to hit stuff HEAD on... it's just his nature

Funny, the two of us ride the same terrain, pretty much same riding aside from me being skis up a bit more (146 vs 154) and I think I hit more crap, he's a way smarter rider than me, but mine have been perfect aside from rod ends which I want to fail, and his are bent... really odd.

The one thing though... if you hit THE arm (like catch something between the sled & ski) they're going to bend. Personally I want them to, I still feel a weak arm is better than a bent S module. I know one day he hit a tree pretty good, it left some nice wood in the arm, but THAT day it didn't bend, so random.

I've been happy with my AI arms. Broke 3 rod ends in marginal snow this season, bent one other. It was a fun early season with the reduced paranoia thanks to these disposable rod ends (I buy cheap ones on Ebay for ~$7). Last season I buckled a stocker when a ski clipped a rock, could barely ride the rest of the day, now I just swap the rod end in 10-20 minutes and keep going. They're lighter too, bonus!

The Arms buckle when they need to saving expensive damage. a loaded 750 lb sled hitting a solid object requires something to give,,their are differences in quality in Rod Ends.

Anybody try the cromo arms? Are they any stronger than the ti ones? I'd like something in between the ti and stock personally.

Molys are between Ti and stock, They are lite and bend when needed, Ti are lite but brittle.

What he said. I would go with chromoly arms. Or you could buy a used set like I did for $220 and find out they are titanium. Someone made a mistake! Man are they lite!

I've only got one ride on them, same with a buddy of mine with a rev. They stand up great to trees so far!

Dan at alternative impact is great to work with too! I will gladly but from him in the future.
