Dodge Ram Cummins 6.7L DOC/DPF 2007-2012: OEM 68035061AB

Integrated Emissions Solution for Dodge Ram Cummins 6.7L (2007–2012)

What is it?
The combined Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) assembly for the Dodge Ram Cummins 6.7L engine (model years 2007–2012) with OEM reference 68035061AB is a key emissions-control component. It serves dual functions: the DOC converts hydrocarbons (HC) and carbon monoxide (CO) into cleaner gases, while the DPF captures soot and particulate matter from the exhaust stream. Together, they help maintain cleaner exhaust output and optimal after-treatment system behavior.

Why choose this DOC/DPF assembly?
This integrated unit is engineered to meet original equipment specifications for 6.7L Cummins applications in Dodge Ram trucks from 2007 to 2012. A worn, clogged, or mismatched component can lead to increased exhaust restriction, frequent regeneration cycles, and emissions-related fault codes. Using the correct assembly helps restore balanced exhaust flow, supports reliable system operation, and preserves the integrity of downstream emissions control components.

Key Benefits
✅ Dual-function design combining DOC and DPF in one assembly
✅ Direct-fit compatibility for 2007–2012 Dodge Ram Cummins 6.7L engines
✅ Converts HC and CO and captures soot for cleaner exhaust output
✅ Helps maintain steady exhaust flow and reduce overall restriction
✅ Designed for heavy-duty operating conditions and high exhaust temperatures

Applications
Ideal for Dodge Ram heavy-duty pickup trucks equipped with the Cummins 6.7L engine from 2007 to 2012. This assembly is especially suited for towing, fleet, work-heavy and all-around applications where dependable emissions system behavior is essential.

Installation Notes
Before servicing, allow the exhaust and after-treatment system to cool completely. Remove the existing DOC/DPF assembly and inspect adjacent exhaust piping, sensors and mounting hardware for soot buildup, cracks or damage. Clean the mating surfaces and install the replacement using new clamps, gaskets and seals. After installation, clear any stored emissions system fault codes and verify proper exhaust system behavior via diagnostic checks.

Final Thoughts
If your 6.7L-equipped Dodge Ram is exhibiting increased exhaust restriction, frequent regeneration demands, or emissions-related alerts, replacing the DOC/DPF assembly with the correct OEM-specified unit is a practical step toward restoring clean, reliable exhaust flow. This component plays a crucial role in maintaining emissions-control system integrity and supporting reliable vehicle operation over the long term.
