ride heights?

okay, so when i bought my truck, it was already lifted. it looks like i have a 3 in. spacer lift and a 3in body lift. i think it looks great. i took it wheeling a few weeks after i bought it, and it started making a clanking sound...
turned out to be a loose body mount...

anyways. it got me thinking. the body lift has caused me nothing but trouble... so i was wondering if i took the body and spacer lift off, and went for a straight 6in fabtec lift would that change my ride height? also, would that change the space i have in the wheel wells? i'd kinda like to keep it looking the same, without the bothersome body lift... suggestions?

 

it should be about the same
