I have a 2.5 inch coil lift and Einstein 5100s I think when I ordered them they told me to get the "2 inch " lift ones so that's what I did. I really wanna add the 4 inch plush ride coils but don't wanna buy new shocks. So does anyone know of they would work with the 3 inch ones?

 

Holy auto correct Bilstein not Einstein.

 

I'm rather find of my Einsteins, and my mother...

 

Sure you can use your shocks. You'll want longer ones at some point to utilize all your suspension travel. Your shorter shocks will limit your flex some.

 

I'm sure they will work. they will limit your down travel though.

 

Your going to want the longer shocks for the 4" coils and also some front adjustable lower control arms if you don't have them yet.
