Light Duty DOCs
If your diesel pickup is struggling to complete a regeneration cycle or you’re seeing 'Efficiency Below Threshold' codes like P0420, your Diesel Oxidation Catalyst (DOC) might be reaching the end of its life. Often overlooked until the DPF completely plugs up, the DOC is responsible for generating the heat required to burn off soot.
Whether you’re running a Ford Powerstroke, a Dodge Cummins, or a GM Duramax, a 'face-plugged' or chemically exhausted DOC will eventually lead to a costly engine derate. We carry a variety of premium aftermarket DOCs and combined DOC/DPF assemblies designed to bolt directly into your light-duty exhaust system and restore factory-level performance.
At DPF Super Store, we focus on providing Canadian truck owners with a better alternative to the dealership. All of our light-duty DOCs are sold as brand-new units with no core charges or return shipping to worry about. We ship directly from our warehouses in Vancouver and Toronto, ensuring your parts arrive quickly without the surprise of international duties or customs delays.
If you’re not sure if you need just the DOC or a full assembly, our expert team is ready to help you cross-reference your OEM part numbers—like the common Dodge 52121891AG or Ford 9C3Z5H221B—so you can get the right fix the first time.
