is an AAL the only thing to do after shackles?

Hi there, I'd like another inch in the rear and I was wondering if there was an alternative to doing an AAL? Like some sort of block? I know one can also 're-arch' the leafs, however this is even more expensive.

For an inch or so just do aal.

On a spring under suspension blocks actually lower the truck, not raise it.

like Alec said... if you want to lift it, you're stuck with shackles or an AAL.
Or, if you wanna spend a little bit more money, and get more lift, do a Spring Over conversion.
You could also get lifted leaf packs, but it would be a waste of money for only an extra 1-2" of lift.
