I'd like to comment on a few things.
First MadOgre is right about 3" body lifts. 1" maximum is fine. Another issue with tall body lifts, and IMO worse than the detail issues of lengthening linkages and such, is the cab wiggling and squirming on the frame. Part of the job of the cab is to limit frame flex.
Also hockey pucks are ***** for lifts. They eventually crack and break and you won't know it until your cab starts to move.
Now here is an idea about lifting your 2x. 35 yrs ago when I lived in flatland Sask I used run and jump my trucks through ditches and 85 mph gravel road cruising. Well I used front springs from a big block truck, which have more weight capacity and they lifted the front about level with the rear. The advantages were obvious. The truck totally handled better in every circumstance. 14bolt in back with a locker, 300 hp 350 and a good driver (me) could out do an average driver in a 4x4. Remember this is in the prairies not the mountains where I live currently.
