Have you looked in to threat motorsports or btf fabrication? Threat is a very good economy level beam builder, your money will go far with his products.
But if you're going to tear the truck apart anyways to build it more, I would save my money. My old truck went from stock, to a 5.5 kit, to a mid travel kit, and I bought a long travel kit but never installed it. Should have just done LT from the get go since that is what I wanted all along, instead of spending all that money on other kits.
