Paccar PX8 DOC 2008-2010

Paccar PX8 DOC 2008‑2010 – OEM Emissions Module

What is it?
The DOC (Diesel Oxidation Catalyst) for Paccar PX8 engines from 2008 to 2010 is an emissions control device placed in the exhaust system. Its role is to oxidize hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream before they reach downstream aftertreatment components.

Why choose this OEM DOC?
This DOC is manufactured to match Paccar’s original specifications—ensuring proper exhaust flow, correct backpressure, and long-lasting construction. Using a genuine or spec‑matched unit helps prevent diagnostic errors, performance degradation, or premature failure that often occurs with substandard or mismatched replacements.

Key Benefits
 ✅ Direct‑fit for Paccar PX8 engines (2008–2010)
 ✅ Efficient reduction of HC and CO emissions
 ✅ Maintains optimal exhaust flow and pressure balance
 ✅ Built to handle high temperatures and exhaust stress
 ✅ Compatible with factory emission sensors and diagnostics

Applications
Designed for trucks and equipment powered by the Paccar PX8 engine in model years 2008 through 2010 that require emission compliance and oxidation of pollutants ahead of particulate or catalytic systems.

Installation Notes
Installation should be done by a skilled technician. Begin with a fully cooled exhaust system. Remove the old DOC, preserving sensor and flange integrity. Clean mating surfaces thoroughly. Replace gaskets or seals as needed. Mount the new DOC with proper alignment and torque to Paccar’s specifications. After installing, inspect for leaks, confirm exhaust flow is unobstructed, and clear any emissions‑related fault codes using diagnostics.

Final Thoughts
If your PX8 engine is triggering emissions errors, underperforming, or failing tests due to oxidation issues, installing the correct DOC for 2008–2010 restores emission control integrity. With factory‑level design and build, it helps your engine run cleaner, maintain compliance, and operate reliably over time.
