I have seen some rear leaves packs that don't require hangers to be moved. I can move them if need be but it would be quicker not too. The Skyjacker soft ride look like they provide a 3" lift and they don't say anything about having to move the hanger location. I see a lot of guys using the chevy leaf but don't know what the benefit is over an aftermarket. Maybe beefier/wider? I also see some listing a military wrap. What is that?
