Next step in truck springs?

[Jerry]

I just put our 1200 on a F450 and it rides very nice.  We did put air bags on the truck to level out the truck.  But the back end measures about 2 inches lower than the front.  Looks weird but probably only affects the headlights.  I had the air bags pumped up to 90 psi.  The manufacture says I can put in a max of 100 psi.  I will try that next.   
Would Helper springs be a good idea?

A pal that bought a new 1165 (two years ago) installed Super-Springs helper springs on his 3500 DRW Ram (pre-camper delivery) and it is perfectly level…Seems a better way to go mainly because it avoids a dreaded air bag failure…
