I am really wanting to level out the ride in my 06 Titan 4x4. I have done a little bit of research and it seems like the best way to go about this is to, get the Bilstein 5100 shocks? I have heard just adding the spacers will make your shocks go bad faster? So what is the best method for doing this? If it is the Bilstein shocks, then what shock do I need exactly (part number?)? If you have a link for them that would be great! Also, how much will the two shocks set me back, and what will installation run? Are there any other parts that I will need, or is it just the shocks?
