Compatibility / Fitment:

Fits 13- and 23-gallon, SAE-flange DEF tanks originally fitted with Freightliner header 04-35959-002, 04-35959-001, 04-35959-000, 04-31353-005, 04-31353-004, 04-31353-002 or 04-31353-001. Applications include Freightliner Cascadia, Coronado, 108SD, 114SD, 122SD and M2 trucks, Western Star 4700, 47X, 4900 and 49X trucks, and motorhomes on the Freightliner XC chassis:

Two hard fitment gates apply:

5/16 in DEF suction fitting. Freightliner Cummins trucks with 13- and 23-gallon tanks use two 20 in DuraWRX headers that look alike. This one has a 5/16 in DEF suction fitting. The earlier 2017 version has a 1/4 in suction fitting, and we also stock it. Check the suction line fitting and the Freightliner number on your old header before ordering.

SAE J2587 flange tank. This header bolts to a tank with an SAE J2587 flange. It does not fit hose-bead, six-bolt or bore-seal tanks. Headers for six-bolt and hose-bead Freightliner tanks are available separately, and we also stock them.

Other versions available: DuraWRX 20 in Cummins header with a 1/4 in suction fitting; DuraWRX headers for 10-gallon, 11.5-gallon and 6-gallon Freightliner Cummins tanks.

Common interchanges: Freightliner 04-35959-002 / 04-35959-001 / 04-35959-000 / 04-31353-005 / 04-31353-004.

The DuraWRX ASPFL-2326 is a new 20 in DEF header with a 5/16 in suction fitting for 13- and 23-gallon, SAE-flange tanks on Freightliner and Western Star Cummins chassis. It replaces Freightliner 04-35959-002. Confirm the suction fitting size and the number on your old header before ordering.
