Application & Compatibility
Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:
- MACK > MACK TRUCK
This S300A099 turbocharger is listed for MACK truck applications. Buyers should verify fitment by cross-checking the part number 631GC5170BM against the OEM reference numbers 173317 and 631GC5170AM. These references serve as identification clues for the replacement application. Confirm that the engine code and vehicle production year on your existing unit match these details before ordering. If your old unit displays different casting numbers, contact technical support to confirm whether they correspond to the same S300A099 application. This verification step helps ensure the correct aftermarket replacement is selected for your specific MACK truck setup.
Technical Notes
The S300A099 model is a fixed-geometry turbocharger design. This unit does not feature variable-geometry turbine vanes. Buyers should verify the physical configuration of their existing unit to ensure it matches this fixed-geometry replacement application. Confirm that the turbine housing and compressor housing dimensions align with the S300A099 specification. If your current unit has adjustable vanes, this part number is not the correct match. Use the casting numbers on the old housing to cross-reference against the supplied OEM numbers 173317 and 631GC5170AM. This step helps confirm the correct technical fitment for your MACK truck engine.
