-Fabricate or buy a new front spring hanger (RUF springs are longer requiring the front hanger to be moved forward)
Great list Rot Box! I wanted to note that on my 85 4 runner I was able to use the stock spring hanger. It does need some beefing up.
My only complaint with RUF is that they wrap even with an anti-wrap leaf and a thicker spring in the mix. I do admit that it took me years to notice this. It really is only a factor on the most extreme trails with extremely steep climbs. I would not trade my RUF for any aftermarket springs. I own a set of custom alcans in the rear, so I know what quality springs can do. The only upgrade for me would be to link it.
Keep your old springs and any others you have laying around for tuning purposes later. Add and subtract leaves to change how soft they are and also to increase or decrease lift. Plan on doing this a few times until you like it. Be sure to run the spring clamps! Don't cut them off if you can avoid it. Extend them if necessary. They will increase the life of your springs and help with wrap. I would say you can reasonably get anywhere from 2-5" lift depending on the mix you create. Also put a anti-wrap leaf on from the get go.
By the list that Rot Box gave you I hope you can add up that it is not a cheap swap. The springs themselves are, but the related mods are not!
