TCaseSlipYkElimKt

This kit is a MUST if you installed a 2 in. or taller suspension lift in your 1987-2006 Jeep Wrangler (not needed for body lifted Jeeps). The kit fits all newer production NP 231 transfer cases (1987- up). A Slip Yoke Eliminator Kit (SYE) will eliminate the need to drop your transfer case in order to avoid drivetrain vibrations that are caused by taller suspension lift. The purpose of this kit is to replace the slip yoke portion of the NP 231 with a fixed yoke and CV-style drive shaft assembly. This is the most complete and strongest kit available. The Mega Short SYE (18676.72) is designed to be used in the same lift applications as the other standard SYE kit (2 in. and up). The main advantage to the new Mega Short SYE kit is that it allows for a much longer drive shaft to be used (additional 3 in.). This reduces the angle of the dive shaft and in turn improved bearing and u-joint life, reduces driveline vibrations caused by lifted Jeeps running short drive shafts. It also has a shorter and stronger main shaft design.

These Rugged Ridge transfer case Mega slip yoke eliminator kits are designed to be used in the same lift applications as the other standard SYE kits. The main advantage to these kits is that they allow for a much longer driveshaft to be used--an additional 3 in. This reduces driveshaft angle, improves bearing and U-joint life, and reduces driveline vibrations. They also have a shorter and stronger main shaft design with improved oiling. They will not work with cable-driven speedometers and are not for use on Rubicon models.
