404 U mogg axles would be better choice, but as with any portal design I like them a lot but one thing I don't like is when you rollover you take a big risk of breaking the portal box.
The leverage when the tire strikes the ground is not in a center line with axle, so it will always want to force the box inward when contact happens, so this will normally crack the portal box.
A few ways to combat this is get larger portals like 416 axles, or after market steel boxes, but once that's done at what cost are a set of well built 60/14 bolt that will offer you the same strength and no chance of portal box breaking.
Plus the other down side is making the pinion match and dumping the torque tube design..
You can plug the Humvee portal boxes onto a set of 9" axles, but oiling becomes a slight concern at higher speeds as you need the pinion flipped to make it go forward. Crawling no big deal, short burst your fine, a lot of highway driving I cant see the pinion lasting long.
