Two hard fitment gates apply:
449 mm header, 7-gallon tanks. International Cummins trucks use two different 449 mm six-bolt DuraWRX headers. This one fits the 7-gallon tank. The other 449 mm version fits 10-gallon Autocar tanks and 15-gallon International MV and IC Multi CE tanks, and we also stock it, along with 297 mm and 623 mm headers. Check the Navistar number on your old header or the tank label before ordering.
Six-bolt tank. This header bolts to a tank with a six-bolt flange. It does not fit SAE-flange, hose-bead or bore-seal tanks.
Other versions available: DuraWRX 449 mm header for 10- and 15-gallon tanks; DuraWRX 297 mm and 623 mm six-bolt headers.
Common interchanges: Navistar 4353001C92 / 4353001C91 / 4254211C91 / 4157846C91 / 2512842C2.
The DuraWRX ASP-908-2321A449 is a new 449 mm DEF header for six-bolt, 7-gallon tanks on International Cummins trucks, IC Multi CE buses and Nexus motorhomes. It replaces Navistar 4353001C92. Confirm the tank size and the number on your old header before ordering.
