I am going to install my new 8.8 this weekend. I have an SYE in there now, and my old D35. If I place the 8.8 in the same position (and I plan to) as the D35, will the driveshaft have to be lengthened or shortened to fit correctly? In other words, is the 8.8 yoke closer to, or further from the T-case than the D35 is?

No one knows if they had to shorten or lengthen their driveshafts for this application? I'll let you know on Monday then.

Its different for every vehicle man. Most likely you will have to shorten it, cause the 8.8 I believe has a longer snout ;) I can tell you what I did, but it wont help. I did an SYE, SOA on 4 inch pro comps, and 8.8 all at once. My shaft ened up at about 22 inches (I think) but it blew up 500 miles later at the CV (too short, too much lift with harsh ass angle.)

Thank you Keith. Mine is not spring over...for now. I suspect it will end up being a little shorter than it is now. I guess my real question was how much longer is the 8.8 "snout" that the D35.

The pinion "snout" on the 8.8 IS longer than a D35, but I don't know exactly how much. If all else stays the same, your shaft will likely need to be shortened, though you may have enough compression room on the splines to make it a moot point.

For reference, a 8.8 to a 231, my shaft length is about 18 inches, but that's in a SOA application with stock-type springs.

For what its worth, I've always heard that its an inch longer. Its not firsthand experience but its the closest answer you've got so far.

MY D-SHAFT IS 18" ALSO. FROM A 231 TO A D35.
JUST GOT MY 8.8 YESTERDAY. PLEASE LET ME KNOW WHAT YOU COME OUT WITH, BEFORE AND AFTER.:beer: :beer: :beer:

the best solution ive come up with would be to use a actual yoke and not an adapter the yoke will give you a little more room about an inch but it has helped on mine with the flange adapter it was collapsing the driveshaft just a bit to far :smokin:

Thank you gentlemen. The info is great, and I will let you guys know what I came up with and how it went, in case anyone else has similar questions.

snacksnack, WHERE DID YOU GET AN ACTUAL YOKE? AND HOW MUCH$.:confused: :beer: :beer:

Good luck, I couldnt find one. Dont remember what I needed, but I ended up going with the ford mounting plate yoke thingie majiggie ;) You want it shorter? Go t18 atlas :p

Well, the axle is in. The driveshaft is too long. Fun driving home in front wheel drive with a locker. Anyway, there is a bit of off-set for the 8.8 yoke, as you guys know. How much is too much? The MORE spring perches have three holes. If I move the axle to the rear-most hole, my driveshaft is fine, however, I have a little longer wheelbase that way. Is this position doable? Should I just have the already very short driveshaft shortened even further? As much as I hate to even consider this, a longer shackle set up in the rear "might" be a solution. It would extend the driveshaft a little, and get the pinion angle a little closer to where I would have liked it to have ended up.

I have included many questions, but if you have any advice, I'll appreciate it.

:question: how much lift are you running, and what angle did you put your pinion at :question: :beer: :beer:
