Paccar PX8 DOC 2008-2010

Clean Emissions for PX8 Engines – Paccar PX8 DOC (2008‑2010)

What is it?
The DOC (Diesel Oxidation Catalyst) for Paccar PX8 engines built between 2008 and 2010 is an aftertreatment device that helps reduce exhaust pollutants. It oxidizes hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream before they reach downstream emission components.

Why choose this OEM DOC?
This DOC is engineered to meet Paccar’s original design standards, ensuring proper exhaust flow, optimal backpressure, and long service life. Using a factory‑specified unit minimizes risks of diagnostic faults, reduced performance, or early failure often seen with generic or mismatched replacements.

Key Benefits
 ✅ Drop‑in fit for Paccar PX8 engines (2008–2010)
 ✅ Efficient oxidation of HC and CO in exhaust
 ✅ Maintains proper exhaust flow and pressure balance
 ✅ Built to sustain high exhaust temperatures
 ✅ Compatible with factory emission systems and diagnostics

Applications
This DOC is intended for use in Paccar PX8-powered trucks and machinery from the 2008–2010 era. It’s vital in applications requiring particulate and emission control under both highway and vocational duty cycles.

Installation Notes
A qualified technician should perform installation. Begin with a cooled exhaust system. Remove the old DOC and carefully preserve any sensor connections. Clean mating surfaces and inspect for gasket or flange damage. Replace old seals as needed. Install the new DOC aligned properly, torque fasteners to OEM specs, then check for leaks, confirm exhaust flow, and clear any emission‑related fault codes via diagnostics.

Final Thoughts
If your PX8 engine is throwing emission warnings or showing performance issues, fitting the correct DOC for 2008–2010 restores oxidation function and system stability. With factory-level compatibility, it supports cleaner operation, reliable emission control, and durable performance.
