Help with general leaf springs

Like the title says I need help from those how have the general leaf springs.
What I have now is the 5100's set at 0 with the OME 883x up front and stock 2x1 leafs out back and I am sitting pretty level. What I want to do is get a shell that is around 180 lbs. is what I am being told. So I thought I would do the general heavy duty rear leaf springs for the extra weight. What they are telling me is that those leafs will give me an 1 1/2 of lift. What I need to know is with the weight of the shell will it settle back down to stock height? Any one do this and what was your measurements? Thanks in advance !!

 

Any one ?

 

Just purchased a 2015 Tacoma TRD Off Road, all original suspension. Installing approx 200 lb Snugtop dropped the rear by 3/4 inch. Doesn't answer your question, but gives you another data point. Actually, now I'm interested in gaining back rear height, plus an inch or so. Considering blocks, but leafs are nearly bottomed on the overloads now and already reverse flexed, so I have little reserve carrying capacity.

 

Well it dos tell me how much I'm looking at of sagging. If you are looking at getting back what you lost and wanting a little more then you might want to look at the general HD version. Thanks for your reply that helped.
