Cummins ISX DOC 2014-2017

Emissions Control You Can Count On for Cummins ISX

What Is It?

The Cummins Diesel Oxidation Catalyst (DOC) for 2014–2017 ISX engines is a critical emissions component that reduces harmful pollutants in the exhaust stream. Positioned upstream of the DPF, this unit initiates the aftertreatment process by converting hydrocarbons (HC) and carbon monoxide (CO) into less harmful compounds.

Why Choose the 2014–2017 ISX DOC?

This DOC is built to match Cummins’ original specifications for ISX engines in the 2014–2017 range. It ensures reliable emissions working conditions, compatibility with onboard sensors, and support for proper downstream DPF regeneration—helping maintain regulatory compliance and operational uptime.

Key Benefits

✅ Exact Fit for 2014–2017 ISX Models: Compatible with OEM exhaust assemblies
✅ Hydrocarbon and CO Conversion: Converts harmful gases into water vapor and CO₂
✅ Supports DPF Regeneration: Maintains optimal exhaust temperatures for soot oxidation
✅ Durable Construction: Withstands high thermal cycles and engine vibration
✅ Sensor-Ready Design: Accepts OEM temperature and pressure sensors with no rework

Applications

Ideal for heavy-duty trucks, line-haul tractors, and vocational equipment running Cummins ISX engines manufactured between 2014 and 2017. It’s commonly used in emissions-compliant fleet operations that demand consistent aftertreatment reliability.

Installation Notes

Have a professional technician complete the installation. Ensure the DOC is free from impact damage and properly mounted. Inspect and clean all surrounding sensors and gaskets. After installation, reset system parameters using diagnostic tools and confirm regeneration readiness.

Final Thoughts

The Cummins ISX DOC (2014–2017) is a critical piece of the aftertreatment system, delivering the emissions reliability your engine needs. With OEM-quality fitment and filtration efficiency, it's a solid solution for keeping your Cummins ISX system running clean and compliant.
