This kit is a MUST if you installed a 2 inch 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 inch 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 inch). 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.
The new tone ring is not splined and without a shim between it and the yoke, it will spin. This creates a wandering speedometer, especially under acceleration and highway cruise. The shim you need is .075thickness 1.54 ID 2.25 OD. Always use a new pinion nut (same nut as your dana 30/35/44 diff)and red loctite. Its a great kit, but get this shim and install it the first time.
Does this part fit in my Jeep Wrangler Rubicon 2003?

Will this work with an Oliver rear Drive shaft?
Asked by Casey from on
Casey, as long as your driveshaft is a CV style shaft, then it will work with the Rugged Ridge NP231 Mega Short Shaft Slip Yoke Eliminator Kit. Thanks for the question!
