I am running a 2" spacer in the front. When I originally did it I was running the stock size Monroe Sensatracs and it was not a problem size wise. Now I'm running a set of Skyjacker Hydros made for 3" lift and the fit is not an issue. Also as crappy and cheap as the Skyjacker Hydros are they are worlds better than the Monroe's. Ride's well on and offroad.
