Note: We have designed our heavy duty fixed yoke output shaft with the most current design shaft found in the New Process Gear NP231. This current design shaft was introduced in 1997. Jeep vehicles using the early NP231 can still use our kit, providing that the needle bearings are removed from the stock drive sprockets.
Transfer Case
Introduced in 1988, the Jeep NP231 is a part-time transfer case became the standard for XJ and YJ models. It was also used in six cylinder ZJ models through 1995. Chain driven with a 2.72:1 low range, it’s reliable even with more than stock horsepower applied.
*Some models may require mode fork shift rail to be shortened. Add the Slip Yoke Eliminator to the Wrangler's NP231 transfer case and solve a couple of problems such as changing a damaged drive shaft on the trail without losing all the lubricant, or eliminating the noise, vibration and wear that develops when the NP231 is lifted. Another benefit is the beefier rear output shaft that provides a 54% increase in torque capacity. Other kit components include: specifically designed aluminum rear output housing, bearings, seals, snap rings, bolts and instructions. **CV rear drive shaft is required.
*This package was designed with the YJ, TJ, & XJ in mind. Other applications may incur addition costs due to cost of production.
