Just a heads up......I cracked two sets of 6.17 R/Ps. One was subsatnially cracked and ready to fail(front) and the rear was just starting to crack at the root of the ring teeth.They were Dana/spicer gears.

I warrantied both sets (Thank you Randy's R/P:awesomework: )and carry a full R/P spare in the tow rig.I NEED to check my front again to make sure the teeth aren't trying to fall off....I'd bet they are cracked at the root at least.

My rig is WAY smaller with alot less horse power(3000# & ~325 horse) so I can't see them holding up in yers any better.My plan is to go 5.38 at the diff and a "baby" stack/3oo 4:1 and take some of the load off the diffs.
 
I will try them...If or should I say when they fail I plan to go 5:86 or 5:38 as well....But I got a real good deal from Ben(Illyota) on all this stuff so I will try it out....Besides everyone knows I baby my junk.:redneck: But thanks for the heads up mauler
 
rear all buttoned up....Lube locker gasket and a dynatrac diff cover front next tues

Well I spent the last 4 hours screwing with the pattern and this diff wants to run fairly deep it is better but still a bit deep

So, in the picture, where the wear marks are on the gear, is kinda deep? It almost looks as if there's barely any contact there. ABout where should the contact be?

Illustrations are welcome!
center of ring is the prefered contact area... this set will run fine not sure how well they will hold up to 44s but we will see
 
So it's deep by about a 1/2 inch or so?

The pattern on the ring gear is only off by like 1/4" to 1/2" but that's only a few thousandths of shims to make this difference. You can't always accomplish this. It's more important in my opinion to have a nice "flat" mark on the gear than to have the pattern in the middle of the gear with a sharp edge to it...
I'd run it!:awesomework:
