I measured before and after and you only get about 2.5" of lift not 3". The Calmini lift will give the full 3". But that is all i did, new springs in back, crank torsion bars in front, got an alignment. And those torsion bars can be cranked quite a bit. I was able to fit 285/75/16's (33") with very little trimming with STOCK 16" wheels (I will be doing some more trimming for the rubbing during major articulation). I also did not change my shocks at all. I think it still rides fine. Others might change them out for a better ride. Keep them and see what you think and if you want to chage them, then do.
If you only want about 1" of lift www.independent4x.com sells 1" and 2" coil spacers and you can crank the tortion bars up front to match. However, new OLD MAN EMU springs only cost a little bit more.
Weird, i could not get the link to work either. It does work if you type it in manually.
