Technical Specifications

The inside diameter of 2.165 inches (55.00 mm) is the critical fitment spec for this bearing—this determines whether the bearing seats properly on your driveshaft. The length from hole to hole of 7.480 inches (190.00 mm) and bearing width of 0.906 inches (23.00 mm) are also key dimensions to verify against your original bearing.
