TeraFlex Slip Yoke Eliminator (SYE) Kit for TJ - XJ - YJ - LJ With 231J Transfer Case

Note: Fits 231-J transfer cases only

SKU: 4444401


The TeraFlex TJ / YJ / XJ  and LJ: NP231 Short Shaft Kit increases the rear driveshaft length by 4” eliminating the need for a Transfer Case Lowering Kit in most cases. This Kit help make the Driveshaft angle better to help eliminate angle, and vibration issues. Also includes a larger/stronger output shaft, bearing and rear housing. [Will need to buy a 1310 cv driveshaft in order for this kit to work. We also sell this as a Package that would save you money if you don't already have a  1310 cv driveshaft.
