Navistar MaxxForce 11,13 DOC 2008-2010

High-Performance Oxidation Catalyst for Navistar MaxxForce 11 and 13 (2008–2010)

What is it?
The Navistar MaxxForce Diesel Oxidation Catalyst (DOC) for 2008–2010 engines plays a key role in reducing emissions by converting carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful gases before they move on to other aftertreatment components.

Why choose this DOC?
This DOC is specifically designed for MaxxForce 11 and 13 engines manufactured between 2008 and 2010, providing the correct flow dynamics and oxidation efficiency. Using the proper unit ensures smooth exhaust flow, prevents excessive backpressure, and protects downstream systems like the DPF or SCR from damage.

Key Benefits
✅ Designed for Navistar MaxxForce 11 and 13 engines (2008–2010)
✅ Converts CO and hydrocarbons into safer exhaust compounds
✅ Supports downstream emission control components
✅ Durable construction withstands high temperatures and long use
✅ Direct-fit replacement ensures an easy installation

Applications
Perfect for trucks, buses, and commercial vehicles powered by Navistar MaxxForce 11 or 13 engines from 2008–2010. It serves as the first stage in the exhaust aftertreatment process, improving overall emission performance.

Installation Notes
Before installation, make sure the engine and exhaust system are completely cool. Remove the old DOC and inspect all surrounding pipes, sensors, and seals for wear or damage. Install the replacement using new gaskets, torque all bolts to Navistar specifications, and confirm a secure seal. After installation, clear any diagnostic codes and run a regeneration or drive cycle to ensure proper system operation.

Final Thoughts
For MaxxForce 11 and 13 engines, this DOC delivers reliable performance, strong build quality, and a perfect fit—helping your emissions system operate efficiently and maintain compliance under demanding conditions.
