FJ45SWB, 1F, H55F, 3.70's, 2.5" lift and 255/85-16's.
I can go 85 down the freeway and the drivetrain seems perfectly happy. Takes about a week to get up to speed but I suppose that's not really the question.
The big deal though is that the truck's wheel base is too short and any ruts or grooves in the pavement are not fun at that speed and the truck seems like it could lose complete composure real quick. It's much more relaxing to cruise at 65.
If some kind of emergency avoidance situation cropped up at 85 I'm pretty sure the chances of saving it are not good.
