Advance Adapters Slip Yoke Eliminator for all Jeep NP231 transfer cases. We consider this to be the all around best slip yoke eliminator kit for nearly any vehicle with a 231 transfer case.
If you have a Wrangler with more than 4 inches of lift and/or a raised transfer case, you may want to consider a Teraflex Extreme Short SYE. Call for more details.
If you have upgraded axles and want to run a 1350 series rear drive shaft, you may want to consider our Super Duty SYE. Call for more details.

The PO of my TJ had lifted 3.5", and then when it was undriveable above 60mph he just gave up and stopped driving at speeds above 60. This kit allowed me to put the transfer case back where it belongs and the Jeep drives and accelerates smooth with no vibrations now.
It's a no brainier, this is hands down the best money you can spend on a lifted TJ. Should be considered required with any lift kit, makes such a difference.
