    Specs. If you're sick of steering wheel shake or vibrations, broken U-joints, and other problems after installing 2 inches or more suspension lift in your Wrangler, this Slip Yoke Eliminator Kit for the NP231 Transfer Case, made by Alloy USA, fits the bill for correcting these problems. It replaces the slip yoke with a fixed yoke. This smooths out or eliminates vibration and shaking, boosts U-joint and bearing longevity, and gets rid of the need to drop your transfer case.

    Construction. The Slip Yoke Eliminator Kit, NP231 Transfer Case by Alloy USA is made from strong, lasting materials and comes with a 5 year limited warranty. It functions with Jeeps that have a minimum 2 inch suspension lift. It does not work with either Rubicon models or Wranglers fitted with cable speedometers. The kit includes an output shaft, a speedometer ring, 3 snap rings, an output yoke with nut, a front output seal, a rear output seal, and an upgraded rear output case. The main shaft is shortened, the driveshaft angle is reduced, and oiling is made easier and more effective.

    Application. Fits 1987-2006 Wrangler YJ and TJ models

      Slip yoke eliminator

      Had to have it professionally installed. But afterwards, the shake was gone and the ride felt so much better. Definitely recommend professional install. Worth the money even though I didn't want to spend it

      Works well and does the job.

      This was recommended by my mechanic that installed my 3.25 inch RC lift. I've heard you may be able to get away without one of your 3 inches or a little over on your lift, but for the longevity of the vehicle and not having to constantly replace parts underneath due to the increased angle this is highly recommended. The mechanic that installed the lift said this was fairly straightforward, but did take a little time to install. Glad I went ahead and rounded out my lift the right way by adding this part.

      Great product

      This product came with everything needed, and listed in the description. It was easy to install, with no surprises. I would recommend it to anyone with vibration problems due to 2 inch lift or more. I wish I had done this first, instead of wasting my time and money on other fixes. My lift was a 2.5 inch. I would recommend this product to anyone.

      Excellent!!!

      This product was installed fairly easy. Took a little Mechanical know how to remove the tcase and install the SYE after cracking the case. Only thing I can say is, MAKE SURE YOU HAVE A BIG PAIR OF SNAP RING PLIERS! It will make your life soooo much easier when removing the stock tailhousing.
