As the owner of a shackle lift you are going to have to buy some outrageously long shackles for 2 inches of lift. I bought the biggest ones that Rocky Road Sells and it gave me just enough to stuff some 235/75/15's under my sammy. and it only gave about an inch of lift also you are going to have to correct the steering angle. never really bought different shocks wasn't really enough lift to warrant it.
Just my opinion, not sure what you are going to be using the rig for, but I would pick up this kit if you are looking to lift your samurai.

you will need
to buy lower front shock tabs buy lower rear tabs if you want to gain longer shocks in the rear
here is what my zuki looked like after the shackle lift with 235's

here is what it looked like after the sky's lift with some 32's

Just my opinion but for a budget lift the sky's is an awsome deal. don't forget you will need to buy lower front shock tabs
