2020+ Ford Super Duty 6.8L V8 and 7.3L With Dual OEM Alternators UNDERHOOD 40 cfm System Compatibility

System or Parts affected • V400031 UNDERHOOD 40 Air Compressor for 2020+ F250 – F600 7.3L Gas. Overview • As outlined in the VMAC Application List the VMAC V400031 system is not compatible with 2020+ Model Year Ford F250 – F600 7.3L gasoline powered vehicles that are equipped with Dual OEM alternators. • If the installer determines that a single alternator will fulfill the vehicle’s operational charging system requirements, conversion to single alternator is an option to accommodate the installation of the above UNDERHOOD system. It is the responsibility of the installer of the VMAC UNDERHOOD system to verify that a single alternator will meet or exceed the operational charging demands of the vehicle and its equipment. Poor battery charging, and any problems resulting from charging system alterations, including the removal of the OEM secondary alternator during upfitter modifications are non-warrantable by both Ford and VMAC. The conversion to single alternator will necessitate having a Ford dealership disable the secondary alternator in the software. The secondary alternator, alternator bracket, and dual alternator FEAD belt can remain in place as the OEM bracket and belt will be replaced with VMAC supplied components during the UNDERHOOD 40 install.
