Slip Yoke Eliminator Kit - Heavy Duty - NP 231 Only
18676.60
Stock Jeeps have a slip yoke style output shaft at the rear driveline. This stock design is not conducive to off road use nor the steeper operating angles caused by suspension lifts. To ensure smooth and durable driveline operation, you should convert to a fixed yoke output and install a rear CV driveshaft.
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 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 CV-style drive shaft assembly. This is the most complete and strongest kit available.
