Re: use rear springs for lift?
Rear springs will fit on the front, you just need new shackle hangers, like ones for the rear, since they're wider. I would recommend using them because they're a heavier spring rate, and typically have one more leaf. I have had superlift superrides, and they ride like a brick. I'm much happier with my skyjackers, I'd recommend them to anyone. The construction of the springs is much better too, the spring clamps are of a looser design and the springs have a teflon pad between them, whereas the superlifts don't.
