I took a Kicker Soundstage setup and made my own box to fit it in the truck. Only problem is the box hinders the full opening of the center console lid and the jump seat can not be used. Could have made the box different to make work with the center console better but im ok with how it is now.
Did you do the install or someone else? I know when I installed my headers I had to disconnect the steering rod link (or whatever its called) so maybe they didnt tighten that back up.
Look into the Autometer Dashlink. It plugs into your OBD port and bluetooth's to your phone. I use it to monitor timing, boost, intake temps and other stuff. It does all kinds of things. 140 bucks but by the time you install all the gauges or things to monitor what it does its not a bad deal.
The kit I bought from McGaughys came with spindles and no upper a-arms. Fit perfect with stamped steel arms, no fitment or alignment issues. I didnt use lowering struts yet but am going to in a week or so to get the front down a little more.
Heres my new truck just lowered it this past weekend. Its a 2/4 drop right now with knuckles in the front and an axle flip in the rear. More mods to come in the next few weeks.
