Rough Country 50-7907 Details

Rough Country NP231 Slip Yoke Eliminator is designed to work with Jeep model NP231 transfer cases. These cases use a slip yoke on the rear output shaft of the transfer case instead of having a fixed yoke and a drive shaft with slip splines. This design works fine on the street but once you have lifted your Jeep and installed bigger tires on it, the stress on the slip yoke or rear output shaft is often too much. This Heavy Duty Slip Yoke eliminator kit includes everything to modify your transfer case, this kit does require an extended travel drive shaft, which helps to prevent driveline vibration and the rear output shaft from breaking.

Features

Converts transfer case from slip yoke to a fixed yoke for improved off-road durability and performance.

Components

1-3/8 inch-32 spline rear output shaft
356-T6 heat treated aluminum alloy tailhousing
