Paccar PX6 DOC 2011-2013

Emissions Control You Can Trust – Paccar PX6 DOC (2011–2013)

What is it?
The Paccar PX6 DOC (Diesel Oxidation Catalyst) is a factory-level emissions module built specifically for PX6 engines made between 2011 and 2013. It oxidizes exhaust gases to reduce hydrocarbons and carbon monoxide before they reach downstream emissions hardware.

Why choose this PX6 DOC?
Engineered to Paccar’s original specifications, this DOC ensures proper exhaust flow dynamics, correct sealing, and compatibility with your engine’s aftertreatment system. Using a genuine DOC helps you avoid diagnostic errors, flow restrictions, or excessive backpressure issues associated with off‑spec replacements.

Key Benefits
 ✅ Direct fit for Paccar PX6 (2011–2013) engines
 ✅ Effective reduction of HC and CO emissions
 ✅ Maintains optimal exhaust flow and backpressure for downstream systems
 ✅ Durable construction designed for high-temperature conditions
 ✅ Compatible with factory emissions control logic and diagnostics

Applications
This DOC is used in Paccar PX6-equipped trucks and machinery from the 2011–2013 model years. It’s appropriate when replacing worn or failing emissions parts, or when restoring aftertreatment systems to proper factory specifications.

Installation Notes
Installation should be handled by experienced technicians. Begin with a cold exhaust system before removing the old DOC. Clean flange surfaces, replace gaskets or seals, and install the new unit with correct factory fasteners. Tighten to OEM torque values. After installation, inspect for leaks, verify emissions system status, and clear any faults or codes via diagnostics.

Final Thoughts
If your PX6 engine is showing emissions warnings, failing tests, or degrading exhaust system performance, replacing the DOC with this OEM-grade Paccar PX6 unit restores proper oxidative function, system integrity, and cleaner emissions—keeping you back in compliance and on the road.
