Crown Automotive RT24004 NP231 Slip Yoke Eliminator Kit with Drive Shaft for 87-06 Jeep Wrangler YJ and TJ
Increased Strength: This kit eliminates the weak point of the factory slip yoke design. It features a heavy-duty 32-spline main shaft that can handle significantly more torque compared to the stock unit, reducing the risk of driveline failure during demanding off-road situations.
Reduced Vibrations: The slip-yoke design can cause driveline vibrations at higher speeds. This eliminator kit replaces the slip yoke with a fixed-yoke output housing, resulting in a smoother and more balanced ride quality, both on and off-road.
Improved Driveline Angles: The kit includes a shortened output housing, optimizing driveline angles for lifted Jeep Wranglers. This reduces stress on U-joints and other driveline components, promoting longevity and maximizing performance.
This complete NP231 Slip Yoke Eliminator Kit with Drive Shaft from Crown Automotive has what you need to complete the lift on your Jeep. This kit is designed for YJ and TJ Wranglers with NP231J transfer case and 1310 driveshafts (1994-1995 YJ please check fitment). To maintain the proper driveline geometry on and off-road this kit moves the slip to the driveshaft and fixes the rear yoke in place. A much better solution to the cheaper transfer case lowering kits on the market. Perfect for 2-6" suspension lifts.
Fitment Note : 1994-1995 Wrangler YJ with 1330 U-Joints are required to switch axle yoke

Crown Automotive NP231 Slip Yoke Eliminator Kit with Drive Shaft Reviews
This kit worked great, just make sure to read the notes. My YJ is a 1994 with the 1330 u-joint, I missed the fitment note when ordering to get a new axle yoke for the 1310 u-joint, I went down the o-Riley’s and picked up conversion u-joint spicer number 5-134x. I will order the yoke sometime but for now I am on the road and the vibration from my lift kit is gone.
This is a great kit! It's very easy to install, plenty of resources on YouTube
