Lengthening a Drive Shaft?? Which one?

[ryan13]

I am in need of a longer rear DS after my SYE install and a stock front XJ/ZJ one is about 6" too short.

I know there is a 17" tube and 19" tube DS design. They both have different types of slips in them as well (one is splined, one is not).

Can anyone recommend which style is better/stronger?

I guess I'm confused. As far as I know, all driveshafts on XJs/ZJs used a splined slip on the driveshaft.

I thought the ZJ front driveshafts were an inch or two longer than an XJ auto one. Not sure though.

The only driveshafts that have a larger stub/slip but are still 1310 are the Durango/Dakota front driveshafts (IIRC) that use a 1.375" stub instead of the 1.250" that the XJ/ZJs used.

You're right, I definitely described that wrong. On one of the shafts, the splines go all the way to the "tube" portion of the shaft. The other is just splined on the first 2-3" and then smooth the rest of the way to the shaft.

"S" version vs "X" version

I'll grab some pictures later tonight.

Which engine and trans do you currently have?

Some of the ZJ and WJ shafts are pretty long, but you have to limit yourself to the ones w/o CV end.

I should also note that this is for my 98 ZJ. I know there a fair amount of XJ guys here who have had custom shafts made so I figured it was worth a shot asking here. My XJ was much easier to lift and deal with...

So its a 5.9/46RE/231 combo. I thought I was doing good by putting a SYE in it and turns out I made more work for myself. The front shafts I have in my possession now measure between 31 and 32" with about 1-1.5" of slip showing...I need the length to be around 38" with 1-1.5" of slip showing.

Carolina Driveline may be your best bet. $161 shipped for a custom length/setup last time I used them.

Dave, I just called them. Price was definitely a bit higher than that but very fair so I bit the bullet and just bought one.

$227 for a long travel option vs the $200ish any local shop was going to charge me for just modifying my existing shaft.

Thanks!

you got the front to fit?

Nope... going to have to end up swapping out the flange for the regular yoke and hope that a front will fit. Otherwise I'm out of cash to throw at this turd for now and my trip won't be happening.
