you can look at my signature and see the lift I have. It does great for how I use it and what i need it for. I got 1.5 inches in the front and 2 inches lift in the back from it.
There are a lot of options depending on what your looking for, and you've gotta answer some simple questions:
What all do you use your truck for?
Do you tow any trailers or want to carry a lot of weight?
Do you or will you install aftermarket armor bumpers?
How high of a lift do you want? (note, once you start sometimes it hard to stop!)
If you don't plan on towing or carrying really heavy loads a lot I would suggest a setup like I have currently using TRD Tundra coils with Bilstein 5100s in the front and LC coils and Bilsteins 5125s in the back (I have my lift build link in my signature). If you do want to tow or carry heavy loads I would suggest changing the LC coils for OME ones instead.
