TeraFlex4444400 Extreme Short Shaft Kit (NP231)

installed this on my 92' YJ fit perfectly. solution to use the output yoke as the bearing surface is brilliant. Following the recommended wiring spec the speedo sensor works perfectly and seems to be accurate. I was able to cut 10" out of an XJ front drive shaft and install it. After the install my new drive shaft is 7" longer from u joint - u joint and all the drive line vibration is gone..

This is a really short SYE kit, it is great. I would of gave it 5 stars BUT, the speed sensor failed within 2 months of having it installed, and it set me SPEDO off by 7 mph, It was on spot before the install. It is made nice, and seems to be holding up ok. But two issues knock it down 2 stars,

Pretty good unit I installed for a friend. I have the jb conversions ssye on mine and the jb unit seems a little beefier.

Had a shop install this for me and within 100 miles it leaked. Teraflex offered up a new seal and yoke and again it leaked. They then blamed it on the installation or the transfer case itself. After which they dropped any help, any support. I finally had to cut my losses and put in a different brand and all is well - no leaks. Cost me my initial price as well as another custom sized drive shaft
