NWOR springs

I am considering getting some of the following springs from NWOR. I would like to know if anyone has an idea of how much lift to expect from the 1.5" 95' Toyota pickup springs for my 96 Tacoma. Most people say that the pre tacoma springs give about 1.5" of lift, but i am curious to find out if these give a much larger amount than they advirtise. I would hate to get them and find out they actually give a pre-tacoma 3" of lift and give my tacoma 5+ inches of lift. thanks for any info guys.
