Kit Contents. The Jeep Wrangler Slip Yoke Eliminator Kit contains a short redesigned transfer case main shaft with 18 percent larger spline diameter and delivers 54 percent more torque than the original. It also contains aluminum rear output housing, bearings, seals, snap rings, bolts, and instructions for convenient installation.

Functional Usage. The transfer case main shaft in this Rugged Ridge Heavy-Duty NP231 Slip Yoke Eliminator Kit helps decrease driveline vibration caused by taller suspension lifts. It allows for the use of a longer drive shaft that reduces drive shaft angle and improves bearing and U-joint life.

Fitment. These Rugged Ridge jeep accessories are designed to fit 1988-2006 Wrangler Jeep models.



Mega Short Design. Made from reinforced T6 aluminum, the Rugged Ridge Mega Short Slip Yoke Eliminator kit is designed to convert your NP231 transfer case to a fixed-yoke CV driveshaft connection. The mega short design provides room for a longer driveshaft to reduce the drive line angle and preventing bind and vibrations from larger lifts. Plus, it offers a stronger driveshaft connection point, allowing you to enjoy some serious off-roading, without worrying about snapping your driveshaft.

Construction. This part is designed with strength in mind for the lifted Wranglers. Going from a slip yoke to the fixed CV connection prevents broken driveshafts and U-joints. A new speed sensor is also included to prevent speed miscalculation. There are many parts included in the kit, all provide high quality and performance over stock.

Application. This kit is designed for the 1988-2006 Jeep Wrangler YJ and TJ models equipped with the NP231 transfer case. Lift application applies to suspension lifts only as body lifts do not require drive line corrections.
