I would actually suggest the Suncoast Heavy Duty rebuild kit, just make sure you also get the Billet Input Shaft as well if he does go that route.
This is the setup that I use and I'm putting down 508hp and I pull ~16k in the horse trailer and it has held up remarkably well.
I don't know one thing about the ones that you posted in that link. They might be good, I just don't know. Most of the people that I know go with the Suncoast kit and these are people with equal or more HP then I do.
Oh and I would imagine that the Edge was very much a contributing factor to the demise of the tranny.

This is a very good reason(but not the only one) for staying away from performance devices that offer shift-on-the-fly. People could get away with that with the 7.3, but not with the 6.0.

Good post Tex!
I never heard of the Road Ripper trannys, but it doesn't mean anything. They could be great transmissions. I personally choose the Suncoast for several reasons, when I've had to rebuild mine, mainly because they have great reputation on the 5R110 trannys. I couldn't be happier with my choice. The Suncoast is a great transmission!

Why the box chips kill it, why the tuners dont, why it skips 4th gear when not towing (I think I read that). Ok maybe start with what I and probably a lot that read this understad, put it in gear and drive it, check the fluid, change the fluid etc.... Its very obvious it not grampas farm truck anymore LOL What ever your willing to spend your time explaining. Thanks

In my opinion chips AND tuners kill the transmission. It was designed to live with the stock amount of power. More power hurts it, and no amount of tuning can fix that.
The trans shifts 1-2-3-5-6. In certain cases it can downshift from 6th to 4th instead of 5th. These are the same with tow/haul on or off.
The reason there are six gears is that there are two transmissions inside the case. One is a three speed and the second is a two speed.
1st gear has both gearsets in low range. 3.09:1 and 1:1 equals 3.09:1 (Later TorqShifts have a 3.11:1 first gear, but it works the same way.)
2nd gear has the rear trans still in low with the front trans shifted to 0.71:1. This give an overall ratio of 2.2:1
3rd gear shifts the front trans back to 1:1 and the rear trans shifts to 1.54:1, so the overall ratio is 1.54:1.
4th gear has the front trans in the 0.71:1 ratio and the rear in 1.54:1. This gives an overall ratio of 1.09:1.
5th gear has both transmissions in 1:1.
6th gear shifts the front trans to 0.71:1 while the rear stays in 1:1. This gives the overdrive ratio of 0.71:1.
Notice that 4th gear is 1.09:1 and 5th gear is 1:1. Those ratios are so close that it never makes sense to use both ratios in any shift sequence, so the trans uses one or the other. When the trans is colder than 0°F it will shift 1-2-3-4-6. That and the rare case when downshifting from 6th with your right foot on the mat are about the only times 4th gear is used.
It wasn't possible to make 4th gear ratio useful and keep the other ratios where they needed to be. The trans was designed from the start to be a five speed. The sixth gear just goes along as fallout from the way the trans was designed.

What isn't being taken into account is that with custom tuning, you don't have to change power output and in fact, you can actually decrease it(and some do that, granted they are the minority, but they do do that). Also you can increase efficiency by matching tuning with how you drive(more or less) as they stock tuning doesn't quite do that for everyone. Stock tuning is also one size fits all. You can do this without increase in power output. Now granted the vast majority do have tuning to increase power output, but that's not all that can be done with custom tuning.
