## Overview

The Rough Country NP231 Slip Yoke Eliminator Kit transforms your Jeep’s NP231 transfer case by replacing the vulnerable slip yoke with a fixed yoke, dramatically improving off-road durability and driveline stability. Tailored for 87-06 Wrangler TJ/YJ and 84-01 Cherokee XJ models, this comprehensive kit includes all necessary components and requires an extended travel drive shaft to eliminate vibration and prevent rear output shaft failure. Backed by Rough Country’s 1-year warranty, it’s the essential upgrade for serious Jeep enthusiasts pushing their rigs beyond stock limits.

## Description

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.

Review: Wow perfecto 👌🏻 de lujo ! Se ve de excelente calidad.
Review: The kit was well put together and every part fit as expected. It seems to be a quality kit and the fit and finish is nice. I had no problem installing the kit, the only down side is when it comes to the shifting fork. Depending on the year for you jeep, you will have to cut the longer portion of the shift fork rod so that the case will fit back onto the transfer case. The included instructions did not mention this fact, but if you look on Rough Country's website, it is detailed out. Once cut the case sealed back up and has been functioning fine. Do yourself a favor, and order a rebuild kit while you're in there. It is ease to do and since all the parts are indoor face, rebuild it.

I got this and went to Sharjah and made a custom driveshaft for my cherokee. Saved me lots of time and money on shipping a new driveshaft. Result: Removed 90% of driveline vibrations from the car. ✅ The 10% are because its a jeep. No vibes, no drives.
