Air Bags with Lift Blocks

Quick question I'm sure has been answered before but I didn't find anything in the search. I'm looking at air bags as I do a lot of hauling (Water, hay, wood, etc). Currently the truck has 2" lift blocks of the cheap variety that I cannot stand as they have no locating pin at the bottom so they had been shifting around with the sub par u-bolts the previous owned reused a bunch of times. I replaced the u-bolts and they have been stable but I'm still wanting to replace them with a better option or if the air bags essentially replace the lift blocks then I'm good with that as well.

 

Airbags + hauling =

 

I have airbags and lift blocks. It works for me. I also put in an RC airbag cradle. The airbag is not attached on the bottom. So, if you raise the truck off the ground (a lift or suspension flex) it won’t rip or tear the bag. The cradle did give me more rake so I had to put less air in the airbags.
