Iron Rock Off Road?

[NSW Sparky]

I cant say enough good things about iron rock. I have their double sheer track bar kit, and steering system. When I was out in moab I broke part of the steering system and they overnighted a new part fast and cheep. they are a good bunch of guys.

Coastie is correct. Unless the XJ you are installing the front DS in (as a rear DS) is a manual, in which case you want a V8 auto ZJ front driveshaft. If you have a lot of lift and a manual you may want an I6 ZJ front driveshaft as it is slightly over 2" longer, but I'm not sure - check that info yourself.

Lengths for ZJ front driveshafts, from Dana-Spicer catalog (if anyone has a copy of the Dana-Spicer rear driveshaft catalog, I would be much obliged! I only have the front DS catalog):

96 w/ 4.0 or 2.5, Manual & 231 TC: 28.02"
92.5-95 w/ 4.0 Manual & 231 TC: 28.02"
96.5-97 w/ 2.5 Manual & 231 TC: 29.02"
96-98 w/ 5.2/5.9 Auto & 249 TC: 29.6"
93-95.5 w/ 4.0 Auto & 231 or 242 or 249 TC: 30.53"
92.5-93 w/ 4.0 AW4 & 231/242/249 TC: 30.53"
96.5-97 w/ 4.0 Auto & 249 TC: 31.53"
97-98 w/ 4.0 Auto & 242 TC: 31.75"
96 w/ 4.0 Manual & 242 TC: 31.77"
93-95.5 w/ 5.2 Auto & 231 or 249 TC: 32.87"

These are ordered from shortest to longest for convenience... if you can fill in these blanks with measurements from junkers or something, maybe we should make a FAQ or sticky about it or something with all the ZJ front driveshaft lengths in one place:

96.5-97 w/ 5.2 Auto & 249 TC: ???
95.5-96 w/ 4.0 Auto & 249 TC: ???
96 w/ 5.2 Auto & 249 TC: ???
95.5-96 w/ 4.0 Auto & 249 TC: ???
95.5 w/ 5.2 Auto & 249 TC: ???

So these are for the Zj driveshafts what about Xj driveshafts?

http://go.jeep-xj.info/HowtoSYEconversion.htm im pretty sure that there yoke is the yoke in the link just cut down. Probably cheaper to just get that yoke and cut it down yourself locally.

Junglejuice - I'll post those up tomorrow if I remember. As I recall most of them are a few inches shorter, on the 28-30 inch range but I'm not sure.

The comments above are somewhat conflicting with the information that I got from Iron Rock themselves. I ordered the yoke and driveshaft on Friday to install in my recently lifted '98 w/ AX-15, 231, and Dana 35. They didn't offer any driveshaft options, told me that the driveshaft that came with the "kit" would work fine with my AX-15... didn't matter whether I had the manual or the auto tranny. Never asked what rear-end I was running.

Everything should be here tomorrow. I'll have to make sure the shaft is long enough before I got and cut the output shaft on the T-Case.

Does anyone have any first hand experience as to why it doesn't work with the Dana 35? How much shorter/longer is the driveshaft with a manual vs. auto tranny?

Thanks.

If you can explain to me how I can make the yoke I need from a standard yoke when the standard yoke has no bolt holes would be interesting.
Gojeep used a yoke imported from Tom Woods, not a standard yoke...
