Pinion Yoke, Fixed, 32 Spline, 1310 U-Joint, Tailshaft Housing Included, Steel, Natural, Jeep Wrangler TJ / YJ 1989-2006, Kit

Kit 50-7906 (Driveshaft modifications required) The Jeep NP231 is one of the most commonly used transfer cases today. It is a chain-driven, planetary designed gear box with a low ratio of 2.72 to 1. For the average 4-wheeler, this is a good transfer case. One of the biggest faults of this transfer case is the overall length. At 20+ inches, this creates an extremely short rear driveshaft in the Jeep YJ & TJ Wranglers, which becomes even more crucial when the vehicle is lifted or a transmission swap is performed. In addition to a lift kit installation, larger tires are usually the next upgrade. Strength and driveline angle of the output shaft then becomes a concern. To make the NP231 better suited for these upgrades, we have designed our “Fixed Yoke” kit with the best features available. We manufacture a new one-piece tailhousing that will add 3-1/2” to 4” to your rear driveline length on a YJ, and up to 6” on a TJ.
