Are you planning on a full suspension rebuild, with new springs and shocks? I went with the "Standard Height" springs that Raptor Racing sells. I got KYB Gsa-A-Just rear shocks, but couldn't find any Gas-A-Just shocks for the front, so I went with a different KYB strut insert.
First thing to do, though, is to inspect ALL the rubber bushings for rot. My front sway bar links were so bad I kept the old ones for laughs after I put the new ones in. If you replace the links, you should also replace the cushions that hold the bar itself to the chassis. Same with the rear bar. Check the steering rack bushings, too, as they tend to get soaked in oil over the years, and turn into Jell-O.
The rubber cushions on the bottom of the rear springs take a beating from road dirt and flexing, so check those.
What's your budget? Going to stay with stock wheels and tires?
