Upgrade the drivetrain of your 1987–2006 Jeep Wrangler with the Rugged Ridge 18676.72 NP231 Mega Short Slip Yoke Eliminator Kit. Designed for newer-production NP231 transfer cases, this kit is recommended for Jeeps equipped with a suspension lift of 2 inches or more. It is not intended for applications using only a body lift. By replacing the transfer case slip yoke with a fixed yoke and CV-style driveshaft connection, the kit helps address drivetrain vibrations associated with increased suspension lift and altered driveline angles.
The Mega Short design shortens the transfer case output shaft by 5 inches compared with the original configuration, allowing the use of a longer driveshaft. The additional driveshaft length helps reduce operating angles, which can improve universal joint and driveshaft bearing service life while minimizing vibration in lifted Jeep applications. Its shorter, stronger main shaft design provides a durable solution for demanding off-road and street use. The kit also includes a speed sensor provision for compatible NP231 transfer cases.
Built from steel, the Rugged Ridge 18676.72 is engineered as a complete slip yoke eliminator solution for lifted Jeep Wrangler drivetrains. It delivers the advantages of a fixed-yoke conversion without requiring transfer case drop spacers, helping preserve ground clearance and improve driveline geometry. Professional installation is recommended, and driveshaft length and compatibility should be verified before installation. This product is backed by a limited 5-year warranty and carries a California Proposition 65 warning.
