    • 3 Inches Shorter Than a Standard Slip Yoke Eliminator (SYE) Kit
    • Tone Ring and Electronic Sensor Transmit Speedometer Readings
    • Mechanical Speedometer Cables Must Be Upgraded to an Electronic Speedometer

    Specs. Adding a lift kit to your Jeep Wrangler frees up more space under the vehicle for better ground clearance and big, terrain-conquering aftermarket tires. However, the slip yoke becomes problematic, and can cause vibrations or even crack the 231-J transfer case because of changes in the driveshaft angle. This Teraflex Extreme Short Shaft Kit fixes these problems in style, giving you 7 extra inches of driveshaft while being 3 inches shorter than standard SYE kits.

    Construction. Teraflex offers a standard limited lifetime warranty on most of its products, and this high quality Extreme Short Shaft Kit is no exception. Made out of high quality materials, this kit enables replacing the slip yoke with a fixed yoke, extending the driveshaft by 7 inches and taking up 3 inches less space than the standard SYE (slip yoke eliminator) kit. All the components needed to modify a 231-J T-case are included. Earlier Jeep models that use a mechanical speedometer cable must be upgraded to an electronic speedometer (sold separately) to use this Short Shaft Kit.

    Application. Fits 1987-2006 TJ & YJ Wranglers.

    I installed a 2" lift kit with transfer case drop kit. When I put it in reverse it will pop-out of reverse I did not experience this problem before it was lifted. Will a slip yoke eliminator and CV drive shaft solve this?

    • Thank you for your question! I would recommend uninstalling the transfer case drop and installing the Teraflex 231 Extreme Short Shaft Kit SYE for better shifting. When dropping the transfer case, linkage can be compromised causing difficulty when shifting.

    I have a SYE drive shaft for my 99 TJ, its for a 4''-6'' lift. Collapsed its 14.25'' and extended it is 17.75". Can I use this Extreme short SYE kit for a lift that is in the 2''-3'' range?

    • The use of Teraflex 231 Extreme Short Shaft Kit with your driveshaft and a 2-3" lift would depend on which exact lift size you go with. You would want to make sure the measurements to ensure that it would be a good fit for your Jeep with your lift size.

    Would I be able to still use the factory driveshaft with this kit with 4 inches of lift?

    • Hello, this kit requires the use of a 1310 CV rear driveshaft, which you can find here:

    Hi, I need to buy an eye for my 1997 Wrangler. I figure if I'm getting one installed I may as well get the extreme short kit. The issue is that I don't know if I have an electronic speedometer. Do you know what years have them? What else would I need to have a properly functioning speedo? Thanks

    • Hello, thank you for your question! I do not believe any years came with an electronic speedometer. You will need to purchase a SpeedoHealer or something similar to help you have a properly functioning speedometer.

      Extreme short shaft kit

      My only complaint is that the Install instructions could be more detailed. Product seems great. I have installed it but have months to go before Jeep will be on/off the road

      Exactly what I needed

      This extreme short SYE kit was a breeze to install. It also came with good instructions and does exactly what it says. It was about 3in or so shorter than my standard SYE. This kit was needed for my 1997 wrangler after installing a tummy tuck skid plate to be able to use my current CV rear driveshaft (with the tummy tuck, my CV shaft was too long fully compressed) This kit is also nice for Jeeps with a lot of lift( 6in) because it helps with driveline angles even with the CV. A traditional CV shaft may not work (one made for a standard SYE) and a different length or custom shaft may be needed. Also note, it you have a older Jeep like my 1997, the speedo is no longer a gear in this kit and you will also need a harness and connector of sorts to make the speedo work. Mine is a trail rig so I did not worry about it

      Best Bang for the Buck

      Installed a early version of this kit in 2009 and have had no trouble with it since. Was a little difficult dropping transfer-case and reinstalling it, the rest was pretty straight forward. In 2014 I installed a flanged yoke so I could run a 1350 cv drive shaft and transfer-case park brake never had to crack the case, just change the fluids with good quality synthetic. Ive run this combo thru all types of terrain and beat on them without mercy, always gets me home.
