that's what every truck I've ever driven sounds like. I expect it's normal for your truck as well

 

I just bought a 2011 F-150 5.0 and loving it, well the back speakers are already blown and I don't rock out lol. (oh well)

My truck is pretty dang even level how it is now and I see you have a 2.5 rough country kit. Well i just ordered mine but I got it for all the way around. Will this make it pretty level or should I do a 1.5 inch in the front? Sorry, newbie here. UPDATE nevrmind, my guy got me the kit with new shocks and all that jazz.

Thanks!
