Paccar PX6 DOC 2008-2010

Clean Emissions, Reliable Operation – Paccar PX6 DOC (2008‑2010)

What is it?
The Paccar PX6 DOC (Diesel Oxidation Catalyst) is an emissions control component designed for Paccar PX6 engines manufactured between 2008 and 2010. It filters and oxidizes exhaust gases—reducing hydrocarbons and carbon monoxide—before entering further aftertreatment stages.

Why choose the PX6 DOC?
This DOC is built to match Paccar’s original design for the PX6 engine, ensuring proper fit, flow characteristics, and emission compliance. Using this original equipment component helps avoid fitment issues, exhaust backpressure problems, and diagnostic faults that can occur when using non‑OEM or generic parts.

Key Benefits
 ✅ Direct-fit for Paccar PX6 engines (2008–2010)
 ✅ Reduces HC and CO emissions in the exhaust stream
 ✅ Proper exhaust flow and backpressure support downstream devices
 ✅ Durable construction designed for high-heat operation
 ✅ Maintains system compatibility with engine management & diagnostics

Applications
Found in Paccar PX6‑powered trucks and equipment from the 2008–2010 model years, especially in vocational and medium-duty classes. This DOC is essential for fleets aiming to maintain emission compliance or restore systems after component aging.

Installation Notes
Have a qualified technician perform installation. Ensure the exhaust system is cool and supported. Remove the old DOC, inspect flanges and gaskets for wear or damage, then install the new unit using OEM gaskets and fasteners. Torque all connections as specified by Paccar. After installation, check for exhaust leaks, confirm proper system operation, and reset any emissions-related fault codes.

Final Thoughts
If your PX6-equipped vehicle is failing emissions checks, producing higher pollutants, or experiencing exhaust system faults, replacing the DOC with the original Paccar PX6 DOC (2008–2010) restores proper emissions control and system integrity. Trust the OEM solution for ongoing compliance and engine health.
