SYE questions

[Coachyak]

Hello Folks
I have a 97 TJ 4.0 with a DPG Ultimate lift and 33 inch KO2s.
Im to the point to start planning my SYE, DC driveshaft and rear control arms.
My questions.
1. I have the MML and the 1 inch BL. Should I raise my TC and transmission an inch while I am at it using a spacer bar between the trans and skid? Not planning a TT during this phase. My thought is this would put the drive line back to it near original position and help with shifting in 2nd a 4th. Also, if I did a TT later my DS would not need to be replaced due to being short. Any thoughts?
2. From my research AA SYE seems to be reliable along with TWoods driveshaft, correct?
3. Currie or Savy Control Arms?
4. With a 2.5 lift (OME springs) will I have shock clearance on the perches once I rotate the rear axle ?
5 Will I need a track bar angled bracket for my SKS rear TB?
6 Is a TW front driveshaft a good investment or stick with the OEM At this point ?
Thanks

Tom Wood's can adjust your driveshaft after a TT for less than the price of a new one if you need it. A SYE doesn't effect your front driveshaft

Understood
Was just thinking about doing it at the same time and value of replacing with a better quality part.

Front is already double cardan, if you're worried about it I would just rebuild it with some good Spicer parts personally

Just my thoughts -
1- install the mml and bl , wait on the control arms and SYE . You may not need it with a 2.5” lift

2-the AA sye is good but many prefer the JB Conversions sye

3- go with the Savvy control arms

4-no worries if you don’t end up needing the sye

5-same answer as 4

6- if your front driveshaft is good then don’t mess with it

1. Do you have a transfer case drop right now? I wouldn't worry about raising the drivetrain for the reasons you mentioned. A 1" BL shouldn't be causing shifting issues. If it is there are other solutions.

Mention about your plans to tuck later down the road when you order your new driveshaft. Chances are they can build it to fit your future needs.

2. AA isn't bad. JB Conversions is better. Tom Woods is the best.

4. You won't need to adjust the pinion angle with only 2.5" lift. After that it will depend on how far you tuck.

Thanks
May not have been clear.
All components of the DPG lift including the MML and BL have been installed for 2+ years.
Believe it or not I have never driven another TJ.
I don’t have terrible shake or vibrations but it’s not smooth either.
I can only compare it to a YJ and a CJ 5 I owned years ago.
Maybe I need to drive a rig thats built well to compare it to.

Tom Woods doesn’t make sye’s . He sells the AA sye .
He also sells the Terra sssye . I’ll take the JB Conversions over either one of those

Here’s a comparison of the JB super short to the standard AA

OP only mentioned AA, you stated that you will chose JB over AA
As far as Terra, i scrolled up and down few times through this thread and only see you mentioning it. Your links to terra vs jb are of no relevance here.
Further more, you wrote that many prefer JB over AA, where is this conclusion coming from?

AA makes a lot of great stuff . Their sye included . I’ve read many compliments on this forum about it and the JB . I have yet to read about anyone swapping out their JB for the AA . Quite a few have swapped out the AA for the JB super short to get more driveshaft length . If a tummy tuck could ever possibly be on the table in the future, the JB will save money and effort .

You are not only responding, you are also making statements that have weight when it comes to making decisions.

Post 6, point 2:

That is your thoughts, would be nice to know how you came to that thinking.

Post 10:

You not just responding, you are also supporting your words above, as if one is clearly above the other.
I am yet to understand why would you take JB over AA.

To get more drive shaft length, right, obviously if you need more length you would not swap back, and same thing other way around. So, if people are not compressing their wheel base, maybe that would explain why it mostly goes one way and not the other. And at last, a Tummy Tuck, finally we are getting to something. Out of 6 sentences, at least 1 somewhat explains something.

See, had you simply said that you used poor choice of words, i would have left it at that.
But when you are comparing and stating your bias between subjectively two different items, that do the same thing differently, and as a result have situational advantage or disadvantage, i will start digging for answers, because id like to know what is that you know and i don't.

2. AA isn't bad. JB Conversions is better.

And you sir, why do you think JB is better than AA.

The JB , wheather standard or short, has a a shorter yoke with more clearance than any of the other commonly available sye’s . This equals a longer driveshaft with less joint angle and more droop before binding . It also has a stronger output shaft although that will probably never make a difference in my use .

 

[B34C0N]

When I chose between the two I mostly went off the fact that I liked the JB instructions better. I also vaguely remember liking the JB tone ring setup better.

As you have a 97, you will have to change the speedo connector if you do a super short. You can get the terra kit or Dorman 645-187 to change it.

As if you cant buy that yoke and fit on other SYE

As if everyone is snapping their output shafts left and right on daily bases
