Paccar PX8 DOC 2008-2010

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

What is it?
The DOC (Diesel Oxidation Catalyst) for Paccar PX8 engines manufactured between 2008 and 2010 is a component in the exhaust aftertreatment system. It oxidizes hydrocarbons (HC) and carbon monoxide (CO), reducing pollutants before exhaust reaches downstream emissions devices.

Why choose this OEM DOC?
This DOC is built to Paccar’s original specifications, ensuring proper exhaust flow, correct backpressure, and long-term durability. A genuine or spec‑matched unit helps prevent diagnostic faults, flow restrictions, or early failures that often occur with low‑quality substitutes.

Key Benefits
 ✅ Direct‑fit for PX8 engines (2008–2010)
 ✅ Effective oxidation of harmful exhaust gases (HC & CO)
 ✅ Maintains balanced exhaust flow, avoiding excessive backpressure
 ✅ Durable construction for high heat and demanding conditions
 ✅ Compatible with factory diagnostic and emission systems

Applications
This DOC is used in Paccar PX8-powered trucks and machinery from model years 2008 to 2010. It’s an integral part of the exhaust system, helping ensure emissions compliance in vocational, transport, and fleet applications.

Installation Notes
Have a qualified technician perform the installation. Begin with the exhaust system fully cooled. Remove the old DOC carefully, preserving sensor connections. Clean mating flange surfaces and inspect for damage. Replace gaskets or seals as needed. Install the new DOC, properly aligned, and torque fasteners to Paccar’s specifications. After installation, check for leaks, verify exhaust flow is unobstructed, and clear any emissions-related fault codes using diagnostic tools.

Final Thoughts
If your PX8 engine is triggering emissions warnings, underperforming, or failing environmental tests, replacing the DOC with the proper PX8 (2008‑2010) unit helps restore system integrity and cleaner exhaust. With factory-level fit and design, it supports reliable emissions control and keeps your equipment compliant and dependable.
