Skyjacker Leaf Springs

[daniel3507]

As some of you know im looking to get a 4'' lift for my truck but I want to avoid blocks in the rear if possible. Ive seen skyjacker leaf springs that say they lift 2-4 inches. I thought it was interesting that there is that much of a range in the lift amount. Any thoughts on that? And on some of theirs it says you can remove stock lift block to reduce the lift amount but my truck did not come with blocks in the rear. Are these actually lift springs or stock replacement springs?
Here is a link to the one i am leaning towards
