I just picked one up tonight. It fights in my 82.5" garage with plenty of room. I didn't measure because we got home so late but looked to be around 3".I doubt they did, but I could be wrong. I hope I'm wrong. But it also would not surprise me if the spec number underestimates suspension sag and tire deformation.
I just measured my garage, and it's about the same, almost 83" but anything over 82.5" will be rubbing the top seal. Hmm. A quick measure of my FJ puts it at about 78" so a LC is only an inch or two worse than that. Until I put larger tires on it.
