Great series of photos and info, Bunyan. That setup is high on my drool list to go along with the NV5600 and NP205 conversion I am doing. Eliminate the weak links as much as possible.
It is troubling to see how necked-down the inner shafts still are, though. All the rest of the shaft beef does little good except to offer the illusion of larger (1. 5 inch?) shaft strength.
That has been my objection to the much cheaper EMS setup. But upon seeing the Dynatrac necked shaft, I don't see as their's is any better, just more expensive by almost twice. I suppose the alloy used would be the deciding factor.
From what I can see, is the Dynatrac inner shaft any thicker at all, given the necked down portion, than the stock inner shaft? I wonder why a guy couldn't just weld the two stock axle halves and sleeve together to eliminate the two-piece design if that is the case?
It's a darned shame we have to spend so much money to go back to something that still isn't quite as strong as the real Dana 60's of old. But at least we can get close. Old school was better school. A couple thousand more dollars upgrading the junk coilspring, trackbar, control arm and multi-link steering and suspension, and a guy could have a real truck again.
Thanks for taking the time to photo-chronicle and share a great step-by-step installation for us!
