i rock an 89 XJ with major rear leaf sagging in the back. Its not lifted and i dont want to lift it. My question is what should I do besides installing blocks do they make air suspension to help boost up the back a little bit?

Your best bet will be to replace the springs with OEM replacements (or equivalent.) An unloaded air suspension rides hard and nasty - don't ask how I know (work trucks, previous driver doesn't air down at the end of the day...)
Airbags are nice if you haul quite a bit, and I do suggest them for that application. They'll help your springs last much longer that way! However, I wouldn't use them to make up for spring sag - I'd just replace the springs outright.
Note that AALs (Add-A-Leaf kits) have much the same effect on ride quality as airbags without a load - both serve to increase your spring rate, making the suspension much harder. (Spring rate = # to compress spring 1". A 300# spring means that 300# will deflect/compress the spring 1", while a 400# spring means actually 400# to the inch. The 400# spring is harder, and will ride harsher, than the 300# spring... AALs and airbags both increase the spring rate, somtimes significantly. The greater the increase in spring rate, the worse the ride will get.)
Just replace the wretched things, and use the old leaves to grind yourself a set of utility and field knife blades...
