How to lift a GMC Jimmy truck?

[Sir Joshua]

I have a 1996 Jimmy I would like to lift but i dont have that much $$$ or the know-how to do it. I was looking on a site that has universal lift kits for a descent price. but i dont know if its all i need in the kit. it is just 5" cups for coils and shocks for it. i dont know if i need arms or whatever to make it work right, i also found 3" body lift, i think that should be fine. here are the links for the parts, just let me know if i need anything else, i think i can figure out putting it together if this is all i need.
