John,
You seem to be asking for two different things.

1" lift w/ long travel in a rally suspension is fine, but it would get trashed at the baja 1000. Travel on those rigs is measured in feet, not inches. So are you just wanting a basic Rally suspension that offers you more height over stock w/ good droop travel for some mild jumping? Please clarify.
AST does offer rally suspension. Please email me so we can discuss your specific needs in further detail.
sales@tarsust.comFWIW, Russ has a set of used K-Sport Rally suspension that he is contemplating selling.
Thanks - Jon
