Slip Yoke Eliminators
The Jeep NP231 is a popular transfer case, but it creates a short rear driveshaft. This Advance Adapters fixed yoke kit adds 3" to 4" to your rear driveline length on a YJ, and up to 6" on a TJ. You get a better driveshaft angle, eliminate driveline vibrations, and have a trail ready transfer case. A must for jeep's lifted 3-4" or more.
