How much has you superlift springs settle????

[rex01atv]

I just instaled 10'' superlift springs in front with a 4'' sky offroad rear shackle reversal with 5.5'' rear springs in the rear. The truck is a 3/4 1984 chevy long bed. I noticed that the back is 3/4'' higher than the front??? What should i expect for when the back springs settle??? I have put 400 lbs in the back to help settle??? I cant drive the truck yet, because of needing longer drivelines.
