Oil Pump NV 263 GM XHD Only

This is the only oil pump for the NV263 GM XHD transfer case. It is for the XHD case only as the drive spline is larger than all others. If you've had one of those common 263 "Failures" this is the pump that you need. Combine this with one of our "Problem Fixer" oil pump update plates and you can forget ever having to do this again.
