Bosch 0445120204 Common Rail Fuel Injector 5253221 for Dodge Ram 6.7 Cummins Cab Chassis

1. Product Overview

Brand new Bosch 0445120204 common rail fuel injector for Dodge Ram cab & chassis trucks with the 6.7L Cummins engine — Ram 3500 Cab & Chassis 2007.5–2010 and Ram 4500/5500 Cab & Chassis 2008–2009. Its group main Cummins number is 5253221; the Cummins numbers 3970987 / 3999832 / 4940096 / 4981077 and the Mopar numbers are shared across the whole cab & chassis group (0445120071 / 0184 / 0204) and are not exclusive to this number, so order by the Bosch number engraved on your old injector. ⚠ Critical warning: this injector uses the same nozzle (0433172155 = DLLA143P2155) and the same control valve family as 0445120161, but the applications are completely different — 0161 is for Cummins ISBe engines (OE 4988835), while this injector is for Ram 6.7L cab & chassis trucks. The complete injectors are NOT interchangeable. This part is for cab & chassis models only, not for regular 6.7L pickups. Bosch parts data lists two valve numbers together for this part (F00RJ02004 and F00RJ01714); which one is the valve assembly on a given unit is confirmed by the number on the old valve.
