Needing to get a SYE for my 99' XJ with 5.5" lift. I know there are so many out there to choose from but would really like to get some feedback from a real user. I have a few in mind. Running a 231 TC. What SYE are you running? And what drive shaft? Lenth?

I picked up an AA SYE kit straight from them. You can pick one up for about 2 bills. As far as driveline goes, I went with a Coast Driveline. The guys there were great and we had some good conversations about competitors shafts, no pun...
I took measurements for what I had from yoke to yoke and they walked me through the process of elimination as far as what length I needed.
Of course this depends on what you are running, aftermarket leaf packs, or something custom from Deaver or Alcan to say a full coil conversion.
Most companies such as JE Reel, Coast Driveline and Tom Woods deal with this everyday and that most have some "preset" measurement depending on your overall lift.

 

I was hoping to run a factory XJ front shaft in the rear to save $, but if its not going to be long enough can I have a drive line shop lenthin it using another spare XJ front shaft I have?

Wanting to order the SYE monday morning, so you guys opinion would be great!

 

If you get a front shaft outta a v8 zj it's 2 inches longer than a XJ front shaft... Worked for me on my old jeep,And I'm sure would be cheaper and stronger than an extended XJ shaft, ask me how I know lol

 

I have a NP242 case, so I have to run a HNT until I am done building the NP231 case. But the style your looking at is the ideal setup, its stronger and longer lasting then the HNT (hack and tap)

as for drive-line I have a stock XJ automatic front drive-line as my rear. works great sitting at 5.5" of lift and moved the rear axle back 1 inch. should work just fine for most kits. The hard part is depending on your setup, lift, rear axle it may not be perfect. wont know until you try.

the drive-line above looks like it was extended in a cheap way and the welds broke, this is not normal. Was a hack job. Any Quality drive-line shop would re-tube it with a new tube if its to short, welding in a smaller tube to extend it adds another fail point and is just bad practice IMO.

I'm not doubting it was done in a cheap and horrible way,came to find out Most of that jeep was... Just sharing experiences that's all lol

 

I know. just stating that an extended "modified" drive-line should be as strong or stronger. don't want people reading this and thinking modified drive-lines are junk. but it does happen.

 

Check out iron rock off road.I have there hack&tap kit and have no issues with drive shaft length with 6.5" of lift

 

I had a local drive line shop extend a few shafts for my Samurai in the past . Had a built 350 with 35" boggers and held up great. Its much cheaper also. As long as the shop knows what there doing, I think it will be strong enough also.

 

Great to know!

 

Two of my XJ's have the AA SYE and one has the P.O.R.C. SYE. I see no difference in the two brands. I got a deal on all 3, paid $150 for AA's and $175 for the PORC.

I'm running stock XJ front shafts and have never had an issue, plus they are cheap/easy to find and you only have to carry one spare(it will work front/rear)

 

Works like a champ. Pick and pull and rebuild if necessary.
