Great forum, love all the info.
I've got an 04 silverado with a 7" CST suspension lift kit. My 35" BFG muds when I got them rubbed ever so slightly at very specific times. Getting new Swamper M16 35s which are slightly bigger then 35" so I think I might need another 1-2" to be safe. I was thinking I should add a coil spring spacer, any reason why I shouldn't do this?
