I managed to install a Poly Performance stage III lift over the weekend. More than a budget lift...in addition to springs/shocks, had to install control arms on front/rear, high steer drag link, brake line extensions, some other stuff that I don't recall offhand.
Anyway, I'm not a mechanic and before I started I didn't know what a tie rod was, a draglink, or many other things. Google works wonders. If you can take your time, figure out what parts go where, you should be able to do it. I'm no genius and I managed it. Also helps if you can find a 3-day weekend to get it done. You'll hit a snag that will double or triple the estimated time you'd expect to get done.
Keep in mind you'll need metric sockets/wrenches in sizes from about 12mm-21mm. That delayed me a goodly amount of time figuring that one out.
