Math is not my strong suit but you might just make it.

My garage is 83" tall and I parked it under the opening and measured 6" clearance between the cab and the top of the entrance.

Hope this helps.

OP, I have a 4" RC lift with 33's and I clear 80" parking garage every day at work by about 1" which matches up to the measurements above.
