Shorter shocks/heavier leafs

Hey guys been a while!.....sooo I recently got new tires and had my 18” cosmis wheels powder coated...this being said my new tires are smaller then I expected....so like any normal person I’m gonna lower my truck even more to take up the wheel gap I have now. Sounds good right?....I’m going with a 5” drop block and some 4x4 leafs....here’s my questions. 1. If I get a heavy duty 4x4 leaf spring(like 1.5” lift) will that lower me even more then a standard 4x4 leaf would? And 2. Any info on what shocks to run at 6-7” of drop? I’ve ran the Qa1s before and now have the calmax’s that DJM recommends but I’m afraid after 4-5” I’ll be driving on a compressed shock the entire time so I’d like to find something that would work. Thanks!
