i'm running skyjacker soft-ride 8" springs with cross-over also.
i run 3 diff size tires, 38" swamps, 42" swamps and 38" toyo m/t's, all on 16 incher rims. swamps are kick-a$$ off road, but HORRIBLE on the street. remember back in the day with bias tires how they would be square every morn? wait...
