The Jeep NP231 is one of the most common transfer cases on the trail, but its length leaves a very short rear driveshaft once you lift the Jeep or swap the transmission. This Advance Adapters fixed yoke kit fixes that with a new one-piece tailhousing and a stronger 32 spline output shaft.
Features
- New one-piece tailhousing adds 3-1/2 to 4 inches of rear driveline length on a YJ and up to 6 inches on a TJ
- Longer driveshaft means a better angle and no more driveline vibration
- New 32 spline output shaft is over 50% stronger than stock
- Includes a 1310 series CV yoke, ready to run with a CV style rear driveshaft
- Vacuum actuation for the front hubs; complete installation instructions provided
What is included
- One-piece NP231 tailhousing (Cherokee style)
- 32 spline NP231 output shaft with fixed yoke
