I was thinking of getting a 6" lift but I have 33" tires and I was seeing if anyone elses rolls this set up and Im pretty sure Im going to need a SYE. How would I go about knowing If I need a longer one or what?

Any lift higher then a 4 inch you need a sye and going 6 inch need other things like upgrade steering, longer brake lines and shocks to match the lift.And i would only go long arm lift that high a short arm would ride rough and not flex as much as a long arm can.

@andrewmp6 yeah, The lift im getting is coming with it all. Long arm kit and all. Im Just wondering if Im going to need a specific sye. I know it has to be compatibale with my tcase. But are there lengths?

andrewmp6

The driveshaft length is hard to say unless you have the lift installed and measure what you need.

i'm at 6 1/2 and went with the standard advanced sye...no problems to date, worked out great, i have the 231j tc
i also run 33's, thus far i've seen no need for going 35 or larger...don't want to bother with a gear swap either until i'm sure this is the rig i want to invest deeper into

first question, what transfer case do you have?

JeeperJim27

I have the np231.

Im getting the lift next month. Im just trying to figure out a sye I will need to get before hand.

A standard SYE is all you need, there's no need for a Super-Short or Mega-Short SYE.

So I dont need to get a longer one?

SeriousOffroad

No, why do you think you need a longer Slip Yoke Eliminator?

JeeperJim27

going from a 3" to a 6" I just thought I would need a longer one?

A SYE is used to make the transfercase shorter... this is so the angle is not as bad for the driveshaft. Plus then you can use a double cardon driveshaft which allows you to angle the pinion towards the transfercase.





Imagine the Green with SYE, and the Red without SYE (Exaggerated for effect),

JeeperJim27

So will I need to get a double cv drive shaft?.. Or will this SYE do?

To use any sye kit you will have to use a different rear driveshaft the stock one won't work anymore.

If you have a 231 Transfercase that will work (2 N 4H 4Lo) - if you have a 242 it will not work (you have both "4 Full Time" and "4 Part Time" choices)

Like already said you will need a new driveshaft, many of times a Jeep XJ Front Shaft will bolt right into the Back with a SYE, or I strongly suggest looking into Tom Woods, Tatton, or Rough Country (I understand made by Tom Woods) driveshafts, I myself got a great deal on a pair of Tattons $400 for a pair shipped.
