Stock Jeeps have a slip yoke style output shaft at the rear driveline. This design is not conducive to off road use nor the steeper operating angles caused by suspension lifts. To ensure smooth and durable driveline operation, convert to a fixed yoke output and install a CV drive shaft (style RE1898). A must on all lifts over 3.5 inch. This kit requires the modification of your stock output shaft. Drill and tap included for easy installation. Drive flange is machined from solid Stainless Steel for extreme strength and corrosion resistance.
Nice product. After install no vibration, really smooth drive. I also installed new Rubicon express drive shaft.
Use a grinder and cutting wheel to cut off the shaft. mark with tape,start engine, place transmission in low and let idle. Shaft is easy to cut but lots of sparks
Q: Could you tell me the height from the edge of the case to the end of the yoke? I'm hoping I can still use my old driveshaft (double Cardin) or maybe rebuild a 2nd one I have. Answer this question
A: There isn't really a height difference. The difference is going to be if yours is a Rubicon as this will not work with the stock double cardon. If you have any of the other trim packages and you are just replacing the transfer case it will not change any of the height for you.

Q: What drive shaft do I need to make this slip yoke eliminator work with my 1998 Jeep ZJ 5.9? Answer this question
A: The length of the driveshaft will depend upon the lift that was installed. Once the lift kit is installed with the 231 SYE, the vehicle will need to be sitting on the ground and you will need to measure from u-joint to u-joint to get the correct length needed.

Q: I need to correct my last question: I have a NP 242 tcase out of a 1999 Durango 5.9L going into my 1997 TJ with 4.5" lift and 35" tires. Will this work? Answer this question
A: Hello The tail shaft is different on the Dodge 242. I checked with Rubicon Express and they said no it will not work.

Q: I have the older style np231 with the coned output shaft housing. Does this product come with a new seal flange and output seal that will replace the old cone housing. TY Answer this question
A: Hi Maarvin This is what is referred to as the hack and tap style SYE kit. It does not replace the seal housing you merely cut the factory output shaft in front of the seal, drill and tap the shaft and install the flange yoke. if you need to replace the seal housing you may wish to look at the RUG18676.60 http://jo.my/2mmn5r Thank You
