Moses, I've done no less than 15 full suspension lifts on Jeep Wranglers. At this point I pretty much have it down to a science. Including alignment, shocks, springs, control arms, sway bar links, track bars, track bar brackets,spring correction wedges and bump stops and extended brake lines.
If I'm doing the entire job solo it requires approximately 8-10 hours. With an extra well experienced hand we can trim 1-2 hours off that time.
Hope this helps
Nate
