has anyone installed these springs without moving rear shackle hangers? I just ordered 4" rear leafs from trail gear, got the forward spring hangers, but didn't get the rear shackle hangers. Is this going to be a problem? are the rear shackle hangers absolutely necessary?

 

Ask this on Trail Gears Forum they are always quick to reply to tech questions.

 

If they are 56" long, then you can run a longer rear shackle. I ran a 7" long (3.5" over stock) shackle w/ some 56" long springs:
