Restore Your Cummins Engine's Power and Efficiency When your Cummins engine begins to show signs of turbocharger failure—such as excessive smoke, oil consumption, or a noticeable drop in boost pressure—the core assembly (CHRA) is often the culprit. Replacing the entire turbocharger housing is frequently unnecessary and costly. Technical Compatibility Note This CHRA is specifically designed for Cummins engines utilizing the HE300WG turbocharger platform. Please verify your existing turbocharger identification plate for the following numbers before purchase:

• Precision Balancing: Each core is VSR (Vibration Sorting Rig) balanced at speeds exceeding 150,000 RPM to ensure vibration-free operation and extended bearing life.
• Upgraded Bearing System: Enhanced journal bearings and thrust spacers provide superior oil film retention and resistance to heat soak.
• Direct Fit: Manufactured to exact Cummins/Holset specifications for seamless integration with the original compressor and turbine housings.
