Need some drag racing advice

So not having raced trucks before, curious about something.
Launching in 4 high and the front not disengaging till after your run,... would this not be pretty hard on your 4wd system?
Was always under the belief 4wd should not be used over 45-55 mph and these drag runs are finishing around 100 mph on dry pavement.

Nowhere near as much torque going through the diffs in 4 high, even with a nitrous launch, as there is full throttle in 4 WD Low.

The diffs are a none issue, very robust especially in 4wd where the torque is halved. Same with the trans, the 6r80 was bullet proof and the 10r80 isn't far behind. For me the biggest fear is grenading the transfer case. Every time I launch in 4HI, I'm listening for two things....the sound of a rod punching a hole in my block and the sound of my transfer case littering the ground with its guts. A close third would be the sound of a u-joint shattering like glass.
Fortunately there are plenty of trail blazers who've run into the low 10's with a near stock driveline without too much fuss. Has anyone broken a transfer case in a drag racing setting?
