      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
