Two hard fitment gates apply:
Six-bolt tank. This header bolts to a 6-gallon tank with a six-bolt flange. Earlier 2014-2017 Freightliner 6-gallon tanks use a hose-bead header, which we also stock. Check how your old header is mounted and the Freightliner number on it before ordering.
Cummins engines. This header is set up for Cummins engines. Detroit-powered trucks use a different header, which we also stock.
Other versions available: DuraWRX hose-bead headers for 6-gallon Freightliner Cummins and Detroit tanks; DuraWRX SAE-flange headers for larger Freightliner tanks.
Common interchanges: Freightliner 04-35649-002 / 04-35649-001 / 04-35649-000 / 04-31354-004 / 04-31354-000.
The DuraWRX ASPFL-2324 is a new DEF header for 6-gallon, six-bolt tanks on Freightliner M2, 108SD and 114SD Cummins trucks and M2-chassis motorhomes. It replaces Freightliner 04-35649-002. Confirm the tank mounting and the number on your old header before ordering.
