Front Springs
Front Hanger
Tubes
frame Jigs
Shackles
High Steer or Crossover Steering
Brake Lines (or else relocate your existing ones)
Front U-Bolts and plates or a Flip Kit
Shocks
Shock hoops
Steering stabilizer
Bumpstops
You also might want to get wheel spacers, a front axle, gears, a locker, vented rotors, Longfields/Bellfields/etc., a drive shaft, bigger tires and rims (unless your current ones will work good enough).
For the rear you will need:
Springs
Shocks
an extended brakeline (if necessary)
Possibly a U-Bolt flip kit
Gears to match the front
Possibly a locker
Depending on what springs you go with, you might need:
Front or rear hanger and possible a different set of shackles.
If you plan on bumping your tire size bigger than 33" then you should re-gear. Most of this stuff can be found online in used condition cheaper than just buying a kit. Also, it's ben my experience that the cheaper you go, the more work/ fine tuning you will have to put into your final project. Rears up front will work, but you may have to take the pack apart a few times in order to find the pack you like. If you can't weld very good, find someone who can, and have them help you.
Easy huh?
