Slip yoke eliminator

Do all Jeeps need a slip yoke eliminator? If not what ones don't?

SYE's are generally used when you install a lift kit along with drive shaft mods like cardan joints to lessen the angles between the TC and the pinion.

It depends what type of transfer case you are dealing with. For example, non Rubicon TJs (and many other jeeps) use a 231 transfer case that does require an SYE. Rubicon TJs though use a 241 transfer case that does not require an SYE. Can you be a bit more specific about what you are dealing with?

Should not be needed IMO. I have the F>R swap, and a little extra lift from an 8.8 swap and have no problems at all with driveline angle or vibrations up to 90MPH (not sure the turd can go faster thant that)

The choice to install an SYE should be made by two factors. One is driveline angles and the other is when the suspension is fully slexed up or down how much of the slip yoke on the front of the driveshaft is still on the tail shaft. Many have dropped a driveshaft on the trail. So when you lift you need to decide the need. There are many ways to get the driveline angles correct without an SYE. Tcase drop is the most popular, 1" motormount lift is another could cost a few bucks. The other is to change the shim at the spring perch at the biottom of the spring stack which sets up the pinion angle.
