Need shocks for 72 K10

[blownchevelle]

So I am at a loss here, I have a 72 K10 4x4 that had an old style 4" lift on it, thing rode like there was no suspension it was so rough. So I got the 2" tough country EZ-ride for it and some Rancho 9000 adjustable shocks. I have gone through 3 pair of front shocks since August 2011, and the truck doesn't get driven much. The front end will bounce after a big bump like crazy, the steering wheel doesn't wobble, it has new ball joints. New steering stableizers and alignment. I have tried different air pressure in the tires as well, 31x10.50's

I don't know what to do it seems like the shocks are bad again, I need something budget friendly, I don't off road much, any advice would be much appreciated!
