I'm looking to smooth out my street ride as much as possible (smooth is a relative term with my truck, I realize) and am thinking Bilsteins or Fox, but have no clue which models. Are the nitrogen charged shocks that much better? With Fox, they're referring to dual speed compression, etc, etc. I don't want to dump a bunch of cash for something that Sorry for dumb questions, but I literally am clueless about shocks. I took my measurements since the truck is lifted, etc, but would greatly appreciate a little guidance.
