Unless you have a nitrogen tank laying around, I would let someone who knows what they're doing handle it. Check with your dealer, if they won't, then a place like Carver Performance, who specializes in Fox shocks will do it for a very reasonable price. When you have them installed, have the person doing the work remove the 1/2" top out bumper, that will add another 1" of travel, and lessen any top out harshness.
