RZR 4, new springs or shocks?

so this weekend i noticed how low my RZR 4 sits from the rear, now between me (yes i’m fat), the wife and two kits, i have 650lbs of us, plus speakers, front and rear bumpers, roof, skid plate, coolers etc. and I don’t have enough ground clearance on the big ruts. I have not adjusted my stock shocks though, should i play around with the adjustments there or buy the Racertech spring/lift combo?
