Drive Cleaner: Cummins ISX DOC (2008–2010)
What is it?
The Cummins ISX DOC (Diesel Oxidation Catalyst) for the 2008–2010 model range converts carbon monoxide and unburned hydrocarbons in exhaust gases into less harmful compounds before they reach downstream emissions components.
Why choose this DOC?
Designed specifically for ISX engines produced between 2008 and 2010, this DOC maintains efficient conversion while avoiding excessive backpressure. Installing the correct unit helps protect downstream filters/catalysts, prevents system faults, and supports optimal exhaust balance.
Key Benefits
✅ Tailored for Cummins ISX engines (2008–2010)
✅ Converts CO and hydrocarbons into safer exhaust byproducts
✅ Helps safeguard downstream emissions components
✅ Built to withstand high heat and continuous operation
✅ Direct-fit construction for accurate installation
Applications
This DOC is suitable for heavy-duty trucks, machinery, and vehicles powered by Cummins ISX engines from 2008 to 2010. It functions as the initial oxidation stage in the vehicle’s emission control sequence.
Installation Notes
Allow the engine and exhaust system to fully cool. Remove the old DOC and inspect surrounding pipes, sensors, and seals for wear. Install the replacement with fresh gaskets, torque mounting hardware to Cummins’ specifications, and confirm proper sealing. After installation, clear fault codes and run a drive or regeneration cycle to verify system performance.
Final Thoughts
For your ISX engine, this DOC balances durability, conversion effectiveness, and proper fit—all in one essential component to support your emissions system.
