Saggy Rear end!

[Dad's 73]

I have brand new 4" springs, heavy duty 51/2" shackles, new shocks and 33" tires on a spring under setup. However my rear end is about an inch lower than the front! Add to this a full tank, camping gear and the family and I'm singing la bamba! Are there any products or fixes for this problem?

On my work scouts I use airbags witch sit on the top of the spring and bolt to side of chasirail wen inflated to 90psi you can see the difference I need them for the loads I carry they come from a bilstine-poliair dealer here in sidney thay told me there for a GM pickup so u shouldn't have to mutch trouble in the us. They work well for me.
