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

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.

Super happy with it easy to install solid durable parts this thing should last quite a while even with the way I drive

Súper bien 👌

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.

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.

Works as described

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.

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
