Getting my bilsteins today

I am ordering bilsteins for my 05 dbl cab today. Im going all around my truck and am just curious of what all I need. Im ordering the 4 shocks and that's it so far. I have good coilovers and have a quarter inch top plate spacer already. And also wheres the best place to order them?

 

Down south motorsports was the cheapest I could find and when I had a problem with install they were quick to walk through it over the phone with me.

 

That was definetly cheaper than the website I was looking at! Thanks!
