P700 Do I need heavier springs for can am shocks

[ike775]

I put on the commander shocks on last night, got them used. The rear had a 1.5" spacer on them I did not have anything to take the spacers off so I put the shocks on anyways. I set all 4 shocks to the lowest preload setting the machine feels so freaking tall now. I think they are all stock springs but for the rear do I need to jump up to 225 or 250 lb springs. I carry an artc 45 plus 2 gallons of fuel, and 2 gallons of water, with a bed extender.
Are you guys with the commander shocks sticking with stock springs? What preload are you setting the shocks?

I am running stock springs. I am thinking about a 19 inch limiting strap for the backs. softest preload in back and 1 from sofest in front. This is for a 2 seater
