Paccar PX6 DOC 2011-2013

Emissions Control Refined – Paccar PX6 DOC (2011–2013)

What is it?
The Paccar PX6 DOC (Diesel Oxidation Catalyst) is a factory-spec emissions control component built for Paccar PX6 engines from model years 2011 to 2013. It oxidizes exhaust gases—reducing hydrocarbons (HC) and carbon monoxide (CO)—as a part of the broader aftertreatment system.

Why choose this PX6 DOC?
This DOC is engineered to match the original design of the PX6 engine, ensuring correct backpressure, exhaust flow characteristics, and fitment. Using the genuine part reduces the risk of diagnostic faults, improper emissions readings, and performance issues that can result from using non‑OEM or mismatched components.

Key Benefits
 ✅ Direct-fit replacement for Paccar PX6 (2011–2013)
 ✅ Effectively reduces HC and CO emissions
 ✅ Supports proper exhaust gas flow and aftertreatment performance
 ✅ Durable build capable of withstanding high exhaust temperatures
 ✅ Maintains compatibility with diagnostic and emission control systems

Applications
Used in trucks and equipment powered by Paccar PX6 engines in the 2011–2013 range. It is ideal for medium-duty and vocational vehicles running emission‑compliant operations, especially where replacement or overhaul of exhaust components is required.

Installation Notes
Take careful steps when installing. Cold the exhaust system first, then remove the old DOC. Inspect and clean mating flanges and ports, replace gaskets or seals, and install using factory fasteners. Torque connections to Paccar’s specifications. After installation, check for exhaust leaks, ensure system logic is correct, and clear any emissions-related fault codes.

Final Thoughts
If your PX6 engine is showing emission system warnings, failing inspections, or generating higher-than-normal emissions, replacing the DOC with this genuine Paccar PX6 DOC (2011–2013) restores proper oxidation and system integrity. It’s a reliable, OEM-matched solution to keep your emissions system functioning correctly.
