Ford Powerstroke 6.7L DOC/DPF 2020-2022: OEM LC3Z-5H270-G

Support Reliable Emissions Control with a DOC/DPF Assembly for Ford Powerstroke 6.7L Engines

What is it?
The Ford Powerstroke 6.7L DOC/DPF assembly, identified by OEM LC3Z-5H270-G, is an integrated emissions aftertreatment component designed for Ford Powerstroke 6.7L diesel engines produced between 2020 and 2022. Combining the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) into a single assembly, it helps oxidize harmful exhaust gases while capturing soot particles before they are released from the exhaust system. The 6.7L Power Stroke utilizes an integrated DOC, DPF, and SCR aftertreatment system to meet modern diesel emissions standards.

Why choose this DOC/DPF Assembly?
An efficient DOC/DPF assembly is essential for maintaining proper regeneration, unrestricted exhaust flow, and dependable emissions performance. This assembly is manufactured to match Ford Powerstroke 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 resulting in increased exhaust backpressure, regeneration concerns, or emissions-related warning lights. Replacing the assembly with the correct OEM-matched component helps maintain consistent exhaust treatment and reliable aftertreatment operation.

Key Benefits
✅ Designed for Ford Powerstroke 6.7L engines (2020–2022)
✅ Integrates DOC and DPF functions into one assembly
✅ Helps maintain proper regeneration and exhaust flow
✅ Direct-fit replacement for accurate installation
✅ Built for durability in demanding heavy-duty diesel operating conditions

Applications
This DOC/DPF assembly is used on Ford Super Duty trucks equipped with 6.7L Powerstroke diesel engines from 2020 through 2022. Common applications include F-250, F-350, F-450, and F-550 trucks used for towing, commercial fleets, utility service, agriculture, construction, and other demanding work environments that require dependable emissions control.

Installation Notes
Before installation, allow the exhaust and aftertreatment system to cool completely. Remove the existing DOC/DPF assembly and inspect surrounding pressure sensors, temperature sensors, clamps, and exhaust connections for contamination or wear. Install the replacement assembly using the appropriate mounting hardware and sealing components to ensure proper alignment and a leak-free fit. After installation, verify successful regeneration operation and clear any stored fault codes using approved diagnostic equipment.

Final Thoughts
If your Ford Powerstroke 6.7L-powered truck is experiencing regeneration issues, excessive exhaust restriction, or emissions-related warning lights, replacing the DOC/DPF assembly with the correct OEM component can help maintain reliable aftertreatment performance. The Ford Powerstroke 6.7L DOC/DPF assembly (OEM LC3Z-5H270-G) plays a critical role in supporting efficient exhaust filtration, dependable emissions control, and long-term diesel truck operation.
