I had one on my Rodeo once.

Liked it a lot - the problems I eventually ran into with it: shocks too big (rubbing, etc like what has been mentioned), crossmember super beefy but totally in the way for oil changes, and too-stiff torsion bars.

For what it's worth, I still run the Calmini 3" lift shackles in the rear of my rig. <img src="/forums/images/graemlins/smile.gif" alt="" />
