Upgrading to 37s
You probably already have most of that, though. So yup....taller coils, longer travel shocks, and maybe longer brake lines.
You can get by with factory control arms on a 3.5" lift. So yeah, I'd think just taller springs and maybe new shocks. Could replace the front shaft if you want, but not required. Wouldn't be a bad idea if you already have one. Not sure if you already have it or not, but an adjustable track bar would be good, too. And at least a track bar bracket for the rear. May consider longer front sway bar disconnects if you don't have adjustables. Longer rear sway bar links aren't a bad idea, either, but you can get by without running them at all. And then longer brake lines, or at least drop brackets. I'd go with a set of longer Crown stainless braided lines. Much more durable, obviously longer, and give a more positive brake feel over stock, too.

Yup....I did forget to mention that. Just did mine back in October and it cured the slight DW I had going on. Turns out that when the shop burned on my upper c gussets, they got the knuckles too hot and melted the cheap plastic bushing in my passenger side upper ball joint. Replaced them with a set of Polys and it's all good now.
