Not needed all the time, but 3 inches is considered by a lot of members here to be the cut off for a SYE. There is a zone lift that many have used that is a 4.25 in lift that is 3in springs and 1.25 in body lift that says you do not need a SYE. When I did my 4in, I just went ahead and did the SYE as well because I wanted to get it all done at once and make sure I did not cause myself more problems. You may want to look into the zone lift.
