Slip Yoke Eliminator Kit - NP231 T-Case
This kit is a must if you have installed a 2 inch or taller suspension lift in your 1997-2006 Jeep TJ Wrangler and use your Jeep as intended.(Note: not needed for body lifted Jeeps).
The kit fits all newer production NP 231 transfer cases (1997 up). A Slip Yoke Eliminator Kit (SYE) will eliminate the need to drop your transfer case in order to avoid drive train 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 Double Cardan Joint style drive shaft assembly. This is the most complete and strongest kit available.

Price: $470
(Requires Double Cardan style Driveshaft: http://ozadventure4x4.com.au/node/35)
