Ditto what Pops said about the spacers... I know PRG Products currently does have an additional option or two for shocks and as Pops stated above is currently working on some additional options for us- so unless you absolutely need to swap out shocks now... you might be better served to wait a bit for some even better options that are coming down the pipe. Especially for those of us with auto-leveling.
