Emission Conversion Catalyst for Navistar MaxxForce 11 & 13 (2008–2010)
What is it?
The Navistar MaxxForce DOC for 2008–2010 (for 11 and 13 engines) chemically converts carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful gases before they proceed through the rest of the emissions system.
Why choose this DOC?
This DOC is engineered to match the flow and exhaust conditions of MaxxForce 11 and 13 engines built between 2008 and 2010. Using the correct unit helps maintain exhaust balance, reduces backpressure, and protects downstream components from overloading or malfunction.
Key Benefits
✅ Compatible with MaxxForce 11 & 13 engines (2008–2010)
✅ Converts CO and hydrocarbons into safer emissions gases
✅ Helps protect downstream DPF or SCR subsystems
✅ Built to handle high temperatures and prolonged use
✅ Direct-fit design for precise installation
Applications
This DOC is ideal for trucks, commercial vehicles, and equipment driven by Navistar MaxxForce 11 or 13 engines from 2008 to 2010. It acts as the initial catalytic stage in the emission treatment chain.
Installation Notes
Begin with the engine and exhaust system fully cooled. Remove the existing DOC and inspect connecting pipes, sensors, flanges, and seals for wear. Install the new unit using fresh gaskets, torque bolts to Navistar specifications, and ensure tight sealing. After installation, clear fault codes and run a regeneration or drive cycle to validate proper function.
Final Thoughts
For MaxxForce 11 and 13 engines, this DOC provides the right conversion capability, durability, and system compatibility needed to support effective emission control from the first stage onward.
