Slip Yoke Eliminator for all Jeep NP231 transfer cases. Choose between Advance Adapters or Teraflex brands, both kits are essentially the same design. We consider these to be the all around best slip yoke eliminator kit for nearly any vehicle with a 231 transfer case. This is an especially common slip yoke eliminator for TJ and YJ Wranglers. 

If you have a TJ Wrangler or a YJ Wrangler with more than 4 inches of lift and/or a raised transfer case, you may want to consider a Teraflex Extreme Short SYE. 

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.
