[CSX 4039]

Is this the same kind of suspension in a KMP 427? I'm thinking you're saying it is different? No? How, except for some different sources of equip is this suspesion different from say, a 'glass SAI or ERA?? Does it have the same kind of body roll when in a turn, etc.? Or, is it like JBL or something (in performance if not design)?
