new rear leafs

I am going to be replacing my leave pack pretty soon and I need to know if its just as simple as "out with the old and in with the new," or is there more involved?
Im probably going with the OME pack, i found it for $333

 

yeah....its basically unbolt and remove old, install and bolt up new. make sure you torque everything down pretty snug, then you'll wanna retorque after 100 miles then again at 500 miles on the u-bolts.

It might scare you how lose it can be after it settles a little...

 

Im not gonna have to get longer U bolts am I?
Also what shocks would be good to run with these? I dont want my shock to limit my travel so im not sure what to get
