When fitting the 1280-40, verify the midshaft stub OD matches the 1.181" bearing ID and the crossmember bracket holes are 6.000" center-to-center. The 2.500" center-to-base height positions the bearing above the mounting flange — confirm this measurement against the existing bracket on the specific vehicle.

The 1280-40 spans multiple Nissan and Infiniti 4x4 truck and SUV platforms across a 17-year production window. The 6.000" mount spacing is common to several 1280-series bearings, but the 2.500" height distinguishes this part. Confirm the specific vehicle model, 4x4 drivetrain, and production year fall within the listed applications before ordering.
