Check your 858 Mountain Cats with the IQS shock package. At full extension the Shock reservoir comes in contact with the upper A-arms. Also as was mentioned in another thread the scratcher hits the rear shock adjuster. Supposedly Cat has a fix coming..
858 Mountain Cat Shock Interference
- Thread starter BB36
- Start date
I wonder if they change the shock bushings to spherical bearing type to let the shock rotate slightly it would be enough to clear. A new arm might be cheaper though.
Polaris has some extra warning stickers Cat could use to just stick on the affected areas. Apparently those stickers solve most of Poo’s design and/or part issues. 
I hope this simple, but good catch is the only concern that we will see... but lots of new stuff in the weeds.
They are spherical.
The issues are with the ATAC shocks! Those shocks were on the demo sleds last spring. I had fun changing the settings.
Will the extra $100 for ATAC we worth it now?
You know I had the QS3 on my Alpha and set and forget them. Only time I got off sled to mess with them was for lockout when I was high marking or real deep. No big deal, really.
Cat made the offer to upgrade to IQS too temping for only $100. Regret? We'll have to see what the fix is first and how inconvenient they make it.

I knew there was a reason I didn't snowcheck a new one this year!
Come on BD97 you would of got a Snopro anyways and had a perma-grin all season. lol But by waiting you will get all the little changes / improvements. I am to old to wait! I normally don't buy a first year anything but this sled looks good to me and the changes usually don't happen until year 3 or later at least that's how things have been in the past. I have said this before AC did too many things right for this sled to be bad but time will tell. AC has changed their approach on things and IMHO are doing a better job at addressing issues. Take the Adapt clutch as an example the old AC may have just ran the clutch and stocked extra parts but instead they look to have addressed the issues at least on paper. I like what they did it is just a more robust clutch, once again time will tell. This shock repair will also be an indicator of their approach if it is a simple spherical bearing then they most likely knew about this figured out a repair and are waiting for parts supply instead of holding back production.
I talked to the cat dealer about this at the Utah snow show today and they said cat is working on something to remedy it. They said they were thinking that fox may have messed up on the tolerance or something on the atac shocks which has them clocked wrong as the sleds with regular qs3’s and Ac5 shocks don’t have this interference. You could clearly see that the sled they had there with the ac5 shocks had the reservoirs clocked in towards the bulkhead more so than the mtn cat with atac shocks and there was close to a half inch or so clearance on that sled. The atac shock sled was making contact as it sat there under its own weight
I was at the local sled show yesterday and they had a Mountain Cat with Atac that had between 5 and 6 thousand miles on it (so i was told). One of the engineers sled and there was no clearance with the A arm but I didn't see any damage either. I didn't do a close inspection but nothing obvious jumped out at me. The steering was quite loose but i was told that the production models got updated / stronger steering components. The sled looked pretty good for being beat on for 5k miles.
Picked mine up yesterday as well, agree with what Mafesto just said. The dampner adjuster just needs a few degrees rotation inwards.
Quick question as I have yet to go thru owners manual. While riding and you want to change shock settings, can you do it thru the handlebars or do you have to do it by touching the Garmin touchscreen? That Garmin is next level compared to what the other manufacturers have on their sleds, impressive!

As with previous ATAC sleds, you activate it by pushing the center of the top button on the left, then can scroll left or right to set the dampening. I am guessing with the G8, you can just leave it activated. I always turned mine off after adjusting so I could see my temp gauge.
