need some advice for shock set up

Seemed to be a solid starting point for me

My guess is your front shocks should be about 60-65 PSI and your rear around 140 PSI. The front track shock should have about 10 threads showing below the lock ring. These should get you close.

I got about 75 in my front shocks...same sled, and about 85-90 in my float. Front skid shock is at factory setting. I weigh about 185 geared up

I'm 260lb without gear. On my 2014 162 with the same shocks you have I got a good ride at 70psi in the front, but had a little too much body roll. 75psi fixed that but got a little rougher so somewhere between there is the happy medium. Best deep snow performance leave the front track shock set about stock or so it has 1 turn of preload on the spring. Crank the front track shock up so there's 1" to 1-1/4" of threads under the preload ring to get a lighter front end feel and take hits from holes on the trail better. Best ride on the rear is 140-145psi depending on how aggressive you are. I end up running mine at 150psi though with my big bore to try and keep the ski lift in check.
