Hey guys... I just got my Rusty's 4.5" full pack kit installed a couple of days ago. I've kind of searched around but haven't gotten the answer I'm looking for. Do the springs (front springs or rear leafs) settle much? It seems that they have slightly, but I am just trying to see whats typical. I see a lot of comments on the passenger side sagging over time, and in all honesty... it seems to be like 1/8"-1/4" lower than the other side. I do have a 15" sub and box which is probably helping it out Just looking for any opinions... Thanks guys.
