Jeep model NP231 transfer cases have one glaring weak point. They use a slip yoke on the rear output shaft of the transfer case instead of having a fixed yoke and a drive shaft with slip splines. This design works fine on the street but once you have lifted your Jeep and installed bigger tires on it, the stress on the slip yoke or rear output shaft is often too much. This Heavy Duty Slip Yoke eliminator kit includes everything to modify your transfer case, this kit does require our extended travel drive shaft, which helps to prevent driveline vibration and the rear output shaft from breaking.
Outland 391867660 Slip Yoke Eliminator Kit for Wrangler (NP231)
The Slip Yoke Eliminator Kit from Outland Automotive is a must for any 88-06 Jeep Wrangler YJ/TJ or 88-01 Cherokee XJ models with a 2-inch or larger suspension lift. When a vehicle is lifted, the geometry of the driveline is altered which will often result in driveline vibrations. Over time, these vibrations can lead to accelerated wear and premature failure of u-joints and bearings. The Slip Yoke Eliminator Kit incorporates a shorter and stronger transfer case main shaft with a fixed output yoke, doing away with the failure-prone slip yoke for more reliable off-road performance. The SYE Kit requires use of a CV-style drive shaft which improves driveline alignment over a broader range of suspension articulation and chassis movement. The SYE Kit will not work with cable driven speedometers and includes detailed installation instructions.
This Short Shaft kit is engineered to withstand the increased torque generated by the extreme reduction of the TeraFlex Low231 4:1 Heavy Duty Transfer Case kit. This kit also eliminates the need to lower the transfer case in most cases by increasing the rear driveshaft length by four inches.
