Slip Yoke Eliminator (SYE) Kits Overview


The model of the transfer case will be stamped in to the circular ID tag.

Often referred to as a Slip Yoke Eliminator (SYE) fixed yoke kit, short shaft kit or tail shaft conversion. This kit does not actually eliminate a slip yoke but rather moves it to a different part of the dive train. On the original application the provision for compression and extension of the drive shaft is a function of both the drive shaft slip yoke and the out-put shaft on the transfer case. After the conversion, this provision for compression and extension becomes a function of the drive shaft only.

You will then have a drive shaft that is longer than stock which will reduce joint angles and the ability to use a Constant Velocity (CV) double cardan type drive shaft. This will reduce driveshaft vibrations for smoother operation and a longer life on the related components.

With this conversion you should be able to keep the transfer case at stock height. You will however, want to be sure to pitch the differential so the pinion points more or less directly at the out-put of the transfer case, maintaining a minimal joint angle at the differential end. Any of these conversions will give you a fixed yoke/flange on the rear out-put of the transfer case.

All of these conversions are offered as a complete package that includes everything required to modify the transfer case along with our high quality CV drive shaft. This drive shaft will be built to fit your vehicle and is not a "universal fit" drive shaft. Once you’ve decided which kit you want.

 

Confirm joint size at differental end - always required with Cherokee applications

If you have a Cherokee or a non-stock differential, you need to confirm joint size at differential end.
As an overview, (assuming you have the 231 transfer case) the options and prices are as follows:
  • Super-Short Conversion with CV drive shaft using the XC or XB Slip Yoke & spline stub is $600
     
  • Super-Short Conversion with CV drive shaft using the S Slip Yoke & spline stub is $570
     
  • Super-Duty Conversion with CV drive shaft using the XC or XB Slip Yoke & spline stub is $575
     
  • Super-Duty Conversion with CV drive shaft using the S Slip Yoke & spline stub is $545
     
  • Advance Adapters Conversion with CV drive shaft using the XC or XB Slip Yoke & spline stub is $525
     
  • Advance Adapters Conversion with CV drive shaft using the S Slip Yoke & spline stub is $495

All of the above use a new main shaft for the transfer case which is larger/stronger than the stock main shaft and no core is required.

  • Our conversion which uses a modified stock main shaft with CV drive shaft using the XC or XB Slip Yoke & spline stub is $400 after return of core.
     
  • Our conversion which uses a modified stock main shaft with CV drive shaft using the S Slip Yoke & spline stub is $370 after return of core.
