This kit is a MUST for taller lifted XJ's, YJ's, ZJ's, and TJ's with a NP231 transfer case to eliminate driveline vibrations coming from the factory rear drive shaft. Fits all newer production transfer cases (1987 - up). This kit will eliminate the need to drop your transfer case in order to avoid drive train vibrations that are caused by taller suspension lift kits. The purpose of this kit is to replace the slip yoke portion of the NP 231with a fixed-yoke, CV style drive shaft assembly. This is the most complete and strongest kit available!IMPORTANT NOTE:
If you will be adding the new driveshaft to your order above, you will need to install the SYE first and then call us with the running length measurement so that you get the appropriate length shaft for your application.
