The AAL will stiffen things up a bit, but in terms of rear lift itís a better approach then the block.
My opinion, forget both and do an Icon multi AAL and get and improved ride and your 1.5" lift. There are also other options out there which are similar to the Icon AAL packs, I believe Wheelers sells and Multi AAL I hear rides good too.
Best of luck
I agree with most of this, except for recommending a 1.5 block just for looks, a block will deteriorate the quality of your ride, it will promote axle wrap, so if you want to have the look of an extra inch or two WITH deteriorated ride quality, then a block is the way to go. Since the single aal doesn't cost much more, the benefits far outweigh the cost difference. Benefits being increased load capacity, better flexing, etc.
