If you've lifted your Jeep Wrangler two inches or more with taller suspension, then you need this Slip Yoke Eliminator Kit, which is designed to fit 1987 and later Jeeps with the NP 231 transfer case (not for use with Rubicon models). This kit eliminates the need to drop your transfer case in order to avoid drive train vibrations that are caused by taller suspension lift. The kit replaces the slip yoke portion of the NP 231 transfer case with a fixed yoke and a drive shaft with a CV joint. CSE Offroad offers both the standard and Mega Short kits. The Mega Short kit allows the usage of a drive shaft that is three inches longer, which provides a better drive shaft angle and lengthens the life of driveline parts such as bearings and U joints while also reducing vibration. Also shown here are replacement seals and related parts. Also be sure to see the CV drive shafts that must be used with these Slip Yoke Eliminator Kits. As always, if you have questions about any of the products we sell at CSE Offroad, call us at the phone number above or use the Live Chat feature.
