Technical Notes

The HX85 turbocharger model is a fixed-geometry design, meaning it does not use variable turbine geometry or adjustable vanes. This housing features a two-port exhaust flange with four bolt holes, which is a key visual identifier for verifying the correct replacement application. Buyers should confirm the flange orientation and bolt pattern against their existing unit. Since the input does not specify actuator type or cooling systems, verify these components separately if your application requires them. Technical fitment support is available to help match the housing to your specific Cummins KT306 or C1800 engine configuration.
