If you want reliability keep your lift height moderate at 2.5" or under and buy a quality not a cheap lift kit. If you are limited on funds then go with budget boost (spacer lift). They are also available up to 2.5".
Check out the 2.5" lifts from Rock Krawler, Teraflex, Metal Cloak, AEV and few other for starters. Read some of the existing lift threads so you can get an idea of the problems that arise and how to avoid them.
