sye on d35 to 8.8

Hi guys, I want to get rid of my t case drop and go for an sye. I currently have a d35 but want to upgrade to a 8.8 in the future. I will have the sye installed with the d35 before I do the swap. My question is will I have to modify or buy a different/longer driveshaft when I do intend to do the 8.8 swap or can I just reconnect the driveshaft to the 8.8 without any problems?

You'll probably have to shorten the driveshaft from the Dana 35 to the 8.8. Why not just swap it all at the same time? That's one set of perches and one driveshaft.

If it needs to be shortened than I will wait to do it at the same time, no sense in spending that extra time and money. Thanks for the quick reply

I intalled an AA SYE and Tom Wood's shaft with my 35. Everything was fine when I put the 8.8 in.

I did the same upgrade, but I did mine all at the same time. I also took the opportunity to change the pinion angle.

The pinion on the 8.8 sits further forward than the 35, but it also sits further toward the passenger side. So they more or less cancel each other out.

I did the SYE on mine when I still had the 35, and when I did the 8.8 the slip yoke on the CV shaft never changed on how far it was on the splines.

Agree with this...d35 first with sye and cv shaft...then put in 8.8 with the same shaft.

The 8.8 pinion is only 1/8" longer...and as mentioned before is offset more than the d35 which makes up for it

For those of you that ran CV style shaft with d35, how was the pinion angle setup? I would imagine shims as I really doubt anyone took time to weld perches at correct angle on the d35. Might as well put the time into the 8.8

Same here. I told Tom what my plans where, when I bought them. He told me that it probably wouldn't be a problem. And if it was, he'd adjust it for free.

I think I used 8 degree shims to get the right angle, of course once you go 8.8 you'll be setting the perches so the shims are temporary.

That information helps a lot. I can split the project into 2 parts and have minimal down time. Then give the shims to the next guy.
