Navistar MaxxForce DT, 9, 10 DOC 2011-2013

Engineered for Emissions Reliability: Navistar MaxxForce DT / 9 / 10 DOC (2011–2013)

What is it?
The Navistar MaxxForce DT / 9 / 10 DOC (2011–2013) is a Diesel Oxidation Catalyst built for Navistar’s DT, MaxxForce 9, and MaxxForce 10 engines produced in the 2011 to 2013 window. Its role is to oxidize unburned hydrocarbons (HC) and carbon monoxide (CO) in exhaust gases, turning them into cleaner compounds before they exit the system.

Why Choose the Navistar MaxxForce DT / 9 / 10 DOC (2011–2013)?
This catalyst is designed to match the original exhaust geometry, sensor interfaces, and gas flow demands of the DT / MaxxForce 9 & 10 series. By matching OEM specifications, it minimizes installation issues, preserves system balance, and supports consistent emissions behavior over the engine’s life.

Key Benefits
✅ Factory Alignment: Built to match original mounting points, ports, and exhaust layout.
✅ Heavy-Duty Construction: Capable of enduring high exhaust temperatures and stress.
✅ Cleaner Conversion: Encourages oxidation of HC and CO to lower pollutant outputs.
✅ Operational Stability: Helps reduce fault codes and maintains steady exhaust conditions.
✅ Downstream Protection: Cleaner gas entering filters, sensors, and piping improves their lifespan.

Applications
This DOC is ideal for trucks, buses, and heavy equipment powered by Navistar’s DT, MaxxForce 9, or MaxxForce 10 engines in the 2011–2013 range. It serves fleet, regional, and vocational applications where emissions consistency and component durability matter.

Installation Notes
Although designed as a direct replacement, professional installation is recommended. Ensure all gaskets, clamps, and sensor connections are sealed correctly and aligned. After mounting, clear diagnostic trouble codes and confirm that the control system recognizes the newly installed catalyst.

Final Thoughts
When emissions compliance and reliability are essential, components like this DOC make a difference. The Navistar MaxxForce DT / 9 / 10 DOC (2011–2013) offers a robust, OEM-compatible solution to restore correct exhaust oxidation and maintain confidence in your vehicle’s emission controls.
