You could use stock front hangers, but being they are only .5" shorter than our hanger, only a 1/2" drop. And it would kick your cater out a bit. Also, we only do 1" over stock shackles, which is bare minimum for running a decent flexy spring.

As for less lift, like Bill said, chopping out frame, and reinforcing so you can have steering is an option. A scary option, but its there. You could use 2" springs from Old Man Emu. They are 50 or 60mm lift, I cant remember. That would lower you, but again, the steering is an issue.

You did say you want about 4" of height, Im assuming suspension here. Id recoomend our hangers, and 3" Downey springs. Their fronts are 3", and run about 160 a set. They are not quite as flexy as alcan, but much cheaper. They also dont brake dive much at all, and handle great. They are what we are runing on the front of our new Tacoma. Ive been through the junkyard spring stuff for the front. And having run NWOR, Rancho, YJ, rears, and numerous mods to every one of those, I didnt want to go through the hassle again. Ive literally run 16-20 different front springs. Ive witnessed, and now wheeled the Downeys, and havent found a spring to touch them for all around performance.
