D35 to 8.8 - longer or shorter driveshaft?

When swapping out a d35 to 8.8 axle, how much longer or shorter will my driveshaft need to be? (I realize each vehicle is different... I'm asking in general)

Can I fabricate or modify new spring perches in a way to make up or give an inch instead of modifying my driveshaft?

Does the 8.8 have 1330 series ujoints?

I'm ready to find an axle!

Yes the disc brake 8.8 uses a 1330. You can get the adapter off a drum brake 8.8 and that is 1310. I had a cv shaft with my d35 with 4.5in lift and went to an 8.8 and stretched the rear almost 2 inches and still using same driveshaft. Its close but it works.

Right now I have 2.5" RE lift with a SYE and Tom Woods shaft. All I want to do is swap in a 8.8 and hopefully not have to get my new driveshaft reworked.

I found a 8.8 with 4.10 gears and open diff for $175 and another with limited slip (code 4L10) for $250. A third place wanted $350 for a LSD.

Thanks man! Good to hear.

What year is your YJ? I have a 1330 yoke on my D35. Hopefully that won't matter if I have to find a 1330 pinion yoke for the 8.8

My 1330 shaft worked fine. Take a couple sockets and a big hammer and you can pull the adapter right off the explorer driveshaft in the yard.

I think the yoke distance is only something like 3/8" or 5/8" difference between the d35 and 8.8 with the 8.8 being the longer one.

The best step is to get a new 1330 yoke for the 8.8...

The 8.8 comes with a flange mounted on the pinion, to which a yoke is bolted to. It is 1 of the weak links in the 8.8 swap, since you are relying on 4 small bolts to handle the torque that you are applying to it.

eastcoastgear, has the yoke for the 1330 as well as a 1310 swap for the 8.8 pinion.

Sorry for the hijack, but I have a question about the u-joints too. I'm doing an 8.8 swap soon, and was wondering what I should do. I can either get my driveshaft made for the 1330, get the 1310 flange for the 8.8, or run a 1310/1330 conversion joint. Which would you do? I've heard that 1310s don't seem to break as much, so I'm curious.

Thanks! Are you talking about a real pinion yoke or the flange mounted yoke?

Perfect... Is the 1330 yoke longer or shorter than the flange/yoke combo?

I'm not sure. I just remember reading that somewhere, but overall I think that's the length difference for the driveshaft between the two axles installed. Hopefully someone who knows for sure will chime in as I'm doing research for my 8.8 swap too.

Thats not true. The flange setup is superior imo. Nobody shears the bolts off of the flange. Do you know how many hardcore koh rigs run flange yokes off thier atlas t cases? Or all the big trucks running np205s ? Plus a flange resists spinning over rocks a lot better than a yoke.

The yoke is a waste of money. If your driveshaft is 1330 use the stock adapter off the disc explorer. If you have the 1310 shaft get the adapter off a drum brake explorer. Both should fit with your current shaft.

1330 is stronger than 1310

x2 plus you can grind your flange on rocks with out hurting it too much but with a yoke you will do more damage to it.

I went with the 1310/1330 conversion u- joint from NAPA. My driveline was too long. I had just enough room to put driveline in, but that was with springs not compressed and driveline completely compressed. I have a SYE and currently a Rancho 2.5 lift, and angled the pinion on the 8.8 for future 4" lift. It cost me $45 to shorten & balance driveline enough to work for now but still give me room to extend out for 4". Sorry I don't remember the total length.

Yeah, I'm running a 1330 at the pinion right now. The front of my shaft is a flange which mates to my HD SYE and it is stout. I am getting a disc brake 8.8 so I should be all set. Thanks a lot y'all!
