2005 f150 screw 4x4, which will give me a better ride, a 2.5" autospring leveling kit or the bilstein 5100's adjusted to give me 2" of lift? thanks.

 

The 2.5" AS shouldn't change the factory ride. I have the Bilsteins and they are firmer than factory, but not harsh. If you don't mind spending the extra, I would go for the Bilsteins, they are a nice improvement over the factory shocks.

 

I have both.
AS 2.5 on my 2004
Bilstein's on my 2007

I say go with the 5100's.

You can look at my gallery for pics of both trucks.

 

Go with the Bilstein's, especially if you need shocks anyway. I just did, check out my pic's.

 

so if the shocks are better why does everyone seem to do the leveling kit? just because it's cheaper?

 

Yep.
