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

Preserve Exhaust System Efficiency 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-A, 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 treats exhaust gases by oxidizing harmful emissions and capturing soot particles before they exit the exhaust system. Ford's 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 aftertreatment system is essential for maintaining proper regeneration, unrestricted exhaust flow, and dependable emissions performance. This DOC/DPF 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 leading to excessive backpressure, regeneration issues, or emissions-related warning lights. Replacing the assembly with the correct OEM-matched component helps maintain consistent exhaust treatment and reliable system operation.

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

Applications
This DOC/DPF assembly is used on Ford Super Duty trucks equipped with 6.7L Powerstroke diesel engines from 2020 through 2022. Typical applications include F-250, F-350, F-450, and F-550 trucks used for towing, commercial fleets, construction, agriculture, utility service, and other heavy-duty operations that depend on reliable 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 correct 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, increased exhaust restriction, or emissions-related warning lights, replacing the DOC/DPF assembly with the correct OEM component can help maintain dependable aftertreatment performance. The Ford Powerstroke 6.7L DOC/DPF assembly (OEM LC3Z-5H270-A) plays a critical role in supporting efficient exhaust filtration, reliable emissions control, and long-term diesel truck operation.
