Maintain Complete Emissions Control with a DOC/DPF Assembly for Dodge Ram Cummins 6.7L Engines

What is it?
The Dodge Ram Cummins 6.7L DOC/DPF assembly, identified by OEM 52014099AH, is an integrated emissions aftertreatment component designed for Dodge Ram Cummins 6.7L diesel engines produced between 2007 and 2012. This assembly combines the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) into one unit, helping oxidize harmful exhaust gases while capturing soot particles before they are released through the exhaust system.

Why choose this DOC/DPF Assembly?
A properly functioning DOC/DPF assembly is essential for maintaining efficient exhaust treatment and dependable emissions performance. This assembly is manufactured to match Dodge Ram Cummins 6.7L specifications, ensuring compatibility with factory-installed sensors, regeneration systems, and exhaust components. Over time, soot accumulation, ash buildup, catalyst degradation, and repeated regeneration cycles can reduce system efficiency, potentially causing increased exhaust backpressure, regeneration issues, or emissions-related warning lights. Replacing the assembly with the correct OEM-matched component helps maintain reliable aftertreatment operation.
