I will receive my long awaited Laramie Longhorn ED on 5/26/14. I have been and will remain a stickler for preventive maintenance. I plan to perform an oil with filter change and rear differential fluid change at ~ 500 miles. Has anyone out there added a Mag-Hytec differential cover on one of of the new Ram 1500's with the air suspension? If so have there been any clearance issues? When I perform the fluid changes, I'll be 2 1/2 hours from a Ram dealer. I don't want to find myself in a bind needing a factory gasket to reinstall the old differential cover.
