Requires aftermarket CV-style driveshaft. This kit has a provision for the front axle vacuum actuator found on some NP231 cases.
The Jeep NP231 is one of the most popular transfer cases, but it creates an extremely short rear driveshaft. These fixed yoke kits from Advance Adapters add 3 to 4 in. to the rear driveline length on a YJ, and up to 6 in. on a TJ. This results in a better driveshaft angle, eliminated driveline vibrations, and a transfer case that's ideal for trail use.
