Slip Yoke Eliminator (SYE) Kit for Jeep TJ, YJ, and XJ


  • Jeep TJ Wrangler (1997-2006)
  • Jeep YJ Wrangler (1987-1996)
  • Jeep XJ Cherokee (1984-2001)


  • A slip yoke eliminator kit (SYE) is a must-have for any Jeep that has been lifted. When you lift your Jeep, the angle of the rear driveshaft increases. This can cause driveline vibrations and premature wear. A slip yoke eliminator kit eliminates the slip yoke from the transfer case, which allows you to run a double cardan (cv) style rear drive shaft.
  • A slip yoke eliminator kit also improves driveline performance. By reducing the length of the transfer case tail shaft, a slip yoke eliminator kit allows for a longer rear driveshaft. It also reduces the angle of the rear driveshaft and prevents vibrations and wear. This results in improved driveline performance, especially on or off-road.
  • A slip yoke eliminator kit is easy to install. Most kits can be installed in a few hours with basic hand tools.

Although there are many other brand Slip Yoke Eliminators on the market, we choose to carry the Advance Adapters SYE. We believe Advance Adapters to be the best SYE on the market. Advance Adapters pioneered the design of this SYE and is well known for their high quality transfer cases and transfer case parts. 

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.

Fantastic… should have done it sooner

Service was great. Really fast delivery. Installation was easy. All vibrations are gone. I couldn’t be happier with this mod on 2001 XJ with 4.5” lift. Also got driveshaft and it was great as well.

Relatively Easy Project

I have a 1994 YJ and this transfer case had needle bearings that had to be pressed out, once the transfer case is out of the Jeep, smooth sailing after watching the how to video on the website, now it’s mated to a Tom Woods double cardan drive shaft, works well. This is also a good time to swap out the speedometer gear if one decides to change their tire size
