Your budget option is a ball joint spacer kit that has a differential drop kit and sway bar drop kit included. It is about $75-$85. Then you must ensure that the front shocks can extend the full length of the lower control arms travel. You cannot have the shock be the limiter, the upper control arm droop stops must limit travel, or you risk destroying the lower ball joints quickly from reverse force.
For the rear you can simply buy a longer shackle kit. Everything will be good and flexy. The ball joint spacers, at stock torsion bar spring rate will soften the suspension a bit.
This is the preferred method of small lifts. The OME kit is great, but you are putting in a heavier duty leaf pack, and heavy duty torsion bars and cranking them, which is really no different than cranking the stock ones. It is still a torsion bar crank.
My opinion is to go with the Ball joint spacers, diff drop and sway bar drop kit and some longer rear shackles. Pair that with longer shocks all around and you are going to be happy. Cheap too.
