NOTE: If ordering a custom length driveshaft with SYE, you will need to install the SYE first and then call us with your driveshaft length.
This kit is a MUST for taller lifted XJ's, YJ's, ZJ's, WJ's and TJ with a NP242 transfer case to eliminate driveline vibrations coming from the factory rear drive shaft. 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 NP242 with a fixed-yoke in order to be able to install a CV style drive shaft assembly. This is the most complete and strongest kit available!
The factory NP242 has a 27 spline output shaft that is 1.172" in diameter, this HD SYE kit will convert the output shaft to 32 splines and increase the diameter to 1.375". As we all know more spines typically equates to more strength! Also, the new output shaft will be roughly 3" shorter, meaning you will end up with a longer driveshaft which will aid in reducing the chances of vibrations. The NP242 may be the most versatile T-case ever installed in a Jeep. It has 2WD, full-time 4WD, part-time 4WD, and 4WD low range. The four ranges, with a decent low range of 2.72:1, make it great in all kinds of terrains.
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.
