Detroit Diesel Series 60, DD13, DD15 DOC 2008-2010

Reliable Emissions Support for Detroit Diesel Series 60, DD13 & DD15

What is it?
The Diesel Oxidation Catalyst (DOC) designed for Detroit Diesel Series 60, DD13, and DD15 engines (model years 2008–2010) is a critical emissions-control component. It converts hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream into cleaner, less harmful gases, helping the aftertreatment system maintain consistent and dependable operation.

Why choose this DOC?
Engineered specifically to meet the requirements of Detroit Diesel Series 60, DD13, and DD15 applications, this DOC offers accurate fitment and reliable support for the factory emissions system. A worn, blocked, or inefficient catalyst can lead to elevated exhaust resistance, higher regeneration frequency, or fault codes related to emissions control. Installing the correct DOC helps restore proper exhaust flow and stable system behavior.

Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports downstream aftertreatment components
✅ Helps maintain steady exhaust flow and reduce restriction
✅ Direct-fit design—no modifications required
✅ Built for heavy-duty, high-temperature operating conditions

Applications
Ideal for medium- and heavy-duty trucks, vocational vehicles, coaches, and other equipment powered by Detroit Diesel Series 60, DD13, or DD15 engines from 2008 to 2010—especially where emissions compliance and reliable system operation are essential.

Installation Notes
Ensure the exhaust and aftertreatment system has completely cooled before starting service. Remove the existing DOC and inspect the housing, sensors, and adjacent exhaust piping for soot buildup, cracks, or damage. Install the new DOC using fresh clamps, gaskets, and seals. After installation, clear any stored fault codes and verify proper exhaust system behavior using diagnostic checks.

Final Thoughts
If your Detroit Diesel Series 60, DD13, or DD15-equipped vehicle is showing signs of elevated exhaust restriction, frequent regenerations, or emissions-related system alerts, replacing the DOC with the correct application-specific unit is a practical step toward restoring clean, reliable exhaust flow. This component plays a key role in maintaining emissions-system integrity and supporting dependable equipment operation.
