🚀 Reinvent your Jeep’s drivetrain — conquer trails without compromise!
The Rough Country NP231 Slip Yoke Eliminator Kit upgrades 1987-2006 Jeep Wrangler TJ/YJ and 1984-2001 Cherokee XJ NP231 transfer cases by replacing the vulnerable slip yoke with a fixed yoke. Designed to enhance off-road durability and performance, this kit prevents driveline vibration and rear output shaft breakage, especially when running lifted suspensions and larger tires. It includes all necessary components for installation and requires Rough Country’s extended travel drive shaft. Backed by a 1-year warranty, it’s a must-have upgrade for serious Jeep enthusiasts.

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.

Installed this on my 2000 XJ with the NP231. Install was smooth, no issues. Didn’t come with instructions but loads of YT vids to watch. Slightly larger tolerances on the machining of the output shaft than the OEM I pulled but only a couple thou. Installed it last week and haven’t driven it much. Will update after a couple wheeling trips
