IMO... don't spend money on shocks or suspension work just yet. Give it half a season at least to try to figure out in more detail what you want the shock to be doing versus what it's doing right now.
An exception would be if you KNOW a shock is a problem... example.. my first year riding was 03-04 on a then-new Ski-Doo Rev 800 151. I remember specifically hitting a short but steep uphill (10-12' high) that several in my group went up before me. I picked a fresh line and hit it and got launched off my sled and thrown back into the snow because the front track shock (FTS) had no rebound damping (which is the speed at how fast the shock extends once compressed)... as in, it rebouned WAY too fast. So it was like a pogo stick. It compressed and BOING shot me right off the sled. I replaced it with something (don't even remember now what it was) and it was a huge improvement.
Sleds I've owned/ridden since haven't had that problem so I think they figured that much out. Plus newer sleds all have adjustable shocks to some degree so you can at least try to make them play nice. The fancy FOX ISQ shocks on my Mountain Cat have that lockout feature you can engage with a switch on the bars to prevent the rear track shock from compressing, reducing the chance of the nose of the sled wanting to lift on steep climbs. The IQ3 shocks have that too but it's a manual adjustment you have to get off the sled to set.
My '23 Khaos has the fancy adjustable Velocity shocks. They definitely affect the side-hill ability. When I got the sled, I didn't even know the dealer never properly set them; one side was softer than the other. It was a pain to lift the left ski and much too easy to left the right ski. Once I set them even, I then played with the low speed compression to make it less likely to tip all the way over but NOT want to stay flat on the ground. I got it to "okay" but never perfect. That's when I emailed Ice Age about maybe getting their IQ3 shocks. They asked questions about what I was experiencing and what I wanted, and I told them basically what I wrote above. They replied and said shocks aren't the answer, check out their "Elevate" spindles. So I read up on them and decided it was better to spend $500 on those than $1500 on shocks. I haven't ridden it yet, but I'm hoping it will make the sled more ridable for me.
So the moral of the story is to get more used to it, try to figure out where the problem is, THEN ask people who probably know more than you and see if they agree or have other ideas. Better to take your time and not waste money.
