Getting all my parts together to lift my 04 Escalade AWD. Going to be going with keys up front and 2.5 spacers in the rear. I will be getting rid of the air ride in the rear and replacing it with a set of bilsteins. I have noticed everyone recommends the 5100s but has anyone tried the 5160s? The extra resivour would look pretty trick. Also I have found that people are recommending a part number for dodge ram shocks, why is that? Can I just use the shocks for a Silverado with a 2" lift?
