If you drive a Dodge Ram powered by the 6.7L Cummins from 2007 to 2012, the emissions system plays a big role in both performance and compliance. The Dodge Ram Cummins 6.7L DOC/DPF (2007–2012, OEM 68035061AB) is a combined unit that handles two key steps of exhaust treatment: initial oxidation of harmful gases and trapping of soot from the combustion process. This integrated module is engineered to match factory standards, helping your truck stay efficient, compliant, and dependable mile after mile.
Unlike standalone components, this DOC/DPF assembly works as a coordinated team in your exhaust system — here’s how it benefits your engine and daily driving:
-
Two-in-One Exhaust Treatment – The DOC portion first oxidizes carbon monoxide and unburned hydrocarbons, while the DPF portion captures fine soot particles before they exit the tailpipe.
-
Improves Air Quality – By targeting both gas and particulate pollutants, this assembly helps reduce environmental impact and keeps exhaust cleaner.
-
Protects Engine and Turbo Components – Proper exhaust filtration lowers backpressure and reduces strain on the turbocharger and related systems, which can improve throttle response and longevity.
-
Factory-Grade Fit and Function – As OEM 68035061AB, this DOC/DPF unit is built to exact factory specifications, ensuring the correct fit and reliable operation throughout its service life.
-
Simplifies Service – Replacing the combined DOC and DPF with a single OEM assembly can streamline maintenance and help prevent emissions-related warning lights or derate conditions.
A degraded or clogged emissions assembly can lead to reduced power, higher smoke levels, and diminished fuel efficiency — and in some cases trigger protective engine behavior. The Dodge Ram Cummins 6.7L DOC/DPF (OEM 68035061AB) delivers the integrated emissions performance your truck needs to run clean, efficient, and within regulatory standards. For Ram owners and mechanics seeking a dependable replacement part, Tamerx offers a quality solution designed to support long-lasting engine health and reliable on-road performance.
