Ramboy,
The torque rating on driveline components, and how much your truck is capable of exceeding them, is important of course, but just as important is how you load these components.
For example, in my Jeep, I have a Dana 44 rear axle. The axle shafts are rated @ approximately 5,500 ft. lbs. ; however, with my transfer case in 4 low, the Jeep is capable of putting to the ground approximately 20,000 ft. lbs. of torque, yet I have not broken a rear axle shaft (yet!). If I wanted to, I could snap my axle shafts like toothpicks. They don’t break because 1) I am generally distributing the torque among the 4 axle shafts, 2) rarely is the Jeep outputting the max torque, and 3) I try to use a smooth power increase whenever possible to minimize the force shock on the system.
Bottom line is that you can have an output that exceeds the torque specifications of the components and still use the truck reliably, but you have to understand that you are capable of easily breaking something, and you need to drive accordingly. This puts a constraint on you and how you operate the vehicle, so it’s a compromise.
Additionally, all mechanical systems break, the parameters to consider are the time interval before they break, and the time between breakage. The more you stress the system the sooner it will break, and the smaller the time interval between breakages.
So the answer to your question “…will the driveline and rear-end handle that o. k. ” is that it depends on how you drive the truck.
