I believe the RC spacer for that kit is only 1.5" so he doesn't need anything to high, unless he wants massive OEM rake.check with major spring companies to see if they have anything that fits your bill.
most companies that I trust/ use are all offroad performance orientated so they don't really do anything over 3". That said, I know Dobinson MAY have something you are looking for. If you only need 2.5" lift then I'd say go with Ironman 4x4 rear springs but... they top out at 2.5"
