Slip Yoke Eliminator Kit | Jeep Cherokee XJ (84-01)/Wrangler TJ (97-06)

Fix a Known Weak Point: Jeep models equipped with NP231 transfer cases share one common vulnerability. The factory slip yoke rear output shaft. While adequate for stock street use, this design quickly becomes a liability once suspension lifts and larger tires are added, increasing stress on the rear output shaft and driveline components. Built for Lifted Performance: Rough Country's Heavy Duty Slip Yoke Eliminator Kit replaces the factory slip yoke with a fixed yoke design to dramatically improve driveline strength and reliability. By correcting driveline angles, this upgrade helps eliminate vibrations caused by suspension lifts while allowing the use of a double cardan CV driveshaft for smoother on-road driving and improved off-road performance. Trail-Ready Durability You Can Trust: Constructed from high-strength materials, this kit is engineered to handle the added load and abuse that lifted Jeeps encounter on and off the trail. This kit includes everything needed to properly modify your transfer case and requires Rough Country's extended travel driveshaft, which helps prevent driveline vibration and protects the rear output shaft from failure.

Features

Improved Driveline Strength: Converts the factory slip yoke to a fixed yoke design for increased driveline durability and reliability under load.
Eliminates Driveline Vibration: Reduces vibrations commonly caused by suspension lifts and worn slip yokes for smoother on-road and off-road performance.
Ideal for Lifted Jeeps: Corrects driveline angles on lifted applications and allows the use of a double cardan CV driveshaft.
Heavy-Duty Construction: Manufactured from high-strength materials to withstand off-road abuse and demanding trail conditions.
Bolt-On Installation: Designed for a straightforward install using factory mounting points with no drilling or cutting required.

Notes

For use with NP231 model transfer cases ONLY. Does NOT work with factory driveshafts. An Aftermarket CV driveshaft is required for use. Designed 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.
