for the money, RE seems to have a good rep on both coasts at that height
there's also Black Diamond, Skyjacker, etc, pretty easy to search up on google
even with the RE 4.5 lift, their reccomended backspace, and even though it's really "taller" than 4.5, I rubbed 32 mud tires up front, so I trimmed a good bit and run flareless. I will trim up the back a little and pull the flares off also to match.
so with 4.5 inches and 33's, you're gonna cut if you want to take full use of the suspension, at least that's my opinion
don't forget to factor in a slip yoke eliminator, maybe upgrade to the HD adjustable track bar and mount (I didn't, probably should have), skids for various spots if you don't have them, and I'd say regearing is in your best interest for the long term
my $.02
searching this forum and google will probably help you more
if you run into cost problems, a good 2" BB, skids and agressive 31s will allow you to have lots of fun without the cost of regearing and a more complex/taller lift
