Thanks John,

I won't do anything else than bolt on spacers, seems the most robust route. I was thinking I'd do the tactical armor group bumpers? I don't have any patience, not willing to wait around for the SA bumpers unless the lead time is fairly short. I'm not sure what year those rubicon wheels are, I don't know if that changes the wheel specs. I was thinking 1" spacers, but if you think I can get away with less I'd rather not have tires sticking way considering all the gravel roads we drive. I appreciate all the help.

I was also wondering what an "unlocked chip" is? Is $250 a good deal on that one for sale on jeepcommander.com?

Joe
