Is a 7.25 rear strong enough?

And if you overwhelm one outright on an “all weather roadway surface” (it’s a thing they use on around here on the backroads that is similar to the finish on a concrete bridge because the plow trucks have to maintain primary highways first) by both tires spinning and then catching traction, you’ll split the spider gears clean in half. They make some impressive noises (even while in neutral!) when being pulled onto a rollback after doing that.
