4" tuff country lift springs / greasable bushings / hd shackles do for the front. if you still got the 6.2 in it prb do hd option on the springs .
rear cheep is 4" block
or lift springs but not cheep.
best for ride and flex is bolt on shackle flip . but might require reset of pinion angle .
also if you got time and money rear greasable bushings also.
then good set of quality shocks gas filled tend to ride better.
bolt on raised sterring arm for down on stock front axle /knuckle is good bolt on fix for steering correction.
possible new c/v head rear drive shaft to solve drive line vibrations you might get. some get it some dont.
otherwise its basics and good starter kit and get you goin good.
lots of info / pics / builds in the garage section here in this site search a bit there also.
and welcome to the site
also later on down the road you can ad 1" body lift and new body bushings along with a set of 1" zero rate's on each axle for 1more inch of lift this would get you a total of 6" later on when your ready to go 6" total. also the zero rate's will let you move the axle ahead for more tire to firewall clearence when you go bigger tires.
