Rough Country NP231 Slip Yoke Eliminator Kit for 87-06 Jeep TJ/YJ/XJ - 50-7907

This is a must for any height lift . Don't bother with crossmember shims that do not correct the vibration after a Lift. I have an RC 2.5" Lift and the ride before this install was rough. I've tried correcting all the drivetrain angles but nothing helped. I managed to do this install without removing the NP231 Transfer case from the vehicle. I don't see any reason why you should. With all the youtube vids that I've watched . All had them remove it from the vehicle. Not necessary imo. Took me about 2 hours to remove and install. The ride now is back to stock non lifted jeep. I could not believe how smooth the ride is now. So don't waste your time on shims. Get this kit along with a new double cardan driveshaft and Enjoy the smooth ride again.

Works as described

I love this slip yolk laminator kit put it on the back of my a15 trans had a drive shaft shortened because I have an 8.8 rear end in my Jeep but absolutely helped with the vibration problems I was having would recommend it to anyone

Did a 4” kit on my dad’s jeep. Had crazy vibration even with a tcase drop. This took a couple hours. Used a spare front driveshaft in the back. No more vibration.

Great quality parts in this kit and easy enough to install if you've watched a couple of YT videos. Its very important to note that because you're going from a slip yoke to a fixed yoke on the rear output you will need to order 4 yoke bolts to connect the new output yoke to your new driveshaft as they're not included in this kit, or with most new drive-shafts. Don't get caught short. They are the same size bolts that hold thr front driveshaft onto the front output yoke and cost about $15 for 4 on Amazon.

Get a NP231 Transfer Case Rebuild Kit while you're at it ;)Everything fit perfectly. Worth it if you have a 4" lift or more. Just remember you'll also need a new rear driveshaft and hey, while you're at it, just fork over the money for a new front driveshaft. I suggest Tom Woods. Rebuild the transfer case, install this SYE kit, then measure for your new driveshaft. Lots of YouTube videos out there. I followed JeepSolid because he has a 3-part video on rebuilding an NP231. And then a video on installing this SYE.

I installed mine this weekend, it went together perfectly.When trying to order a new driveline, I went back to the amazon listing to see if it showed the yoke size. I noticed that in the picture the shaft is in the housing backwards. haha, whoops! Pay no attention to the pictures, the kit is great, and comes with everything you need.The biggest difficulty I had was removing the old spring clips. Those things are the devil even with spring clip pliers!

It works
