This really doesnt help anyone out. It pushes people away from posting anything or contributing to the forum later after they have learned something.
Yes there is a suspension thread, congratulations for knowing where it is!
Unfortunately this topic gets beat to death and new threads are created daily from new members on this exact question but I'll be glad to talk ya through any confusion.
For starters, what is your purpose of lifting going to be.. looks?, functionality?, Trophy truck for shows?, to talk shit to jeep guys?
If your going for looks and want to keep the budget low as well as preserve the factory ride. go with a daystar spacer lift. they're inexpensive and most shops can install them without issues..
If your going for functionality, you'll have to decide how much functionality your looking for, Baja racing?, Dirt roads?, or somewhere in between? They have kits that fit just about any need.
Also here is a good site to look into pricing for the different options.
Toytec Lifts - Toytec Lifts: Toyota Lift Kits: FJ Cruiser Lift Kits, Tacoma Lift Kits, Tundra Lift Kits, 4 Runner Lift Kits, Sequoia Lift Kits, Toyota Truck Lift Kits
and for a handy tip: if you raise the front end 3" you'll want to add after market upper control arms in the front setup to allow caster alignments to be set back to factory settings.
let me know what your looking for an I'll do my best to steer you in the right direction
