Additional Notes
- The BCS Invictus 300 AR and 300 RS share an identical front differential fluid capacity of 4.8 liters, a figure that also applies to both the 400 AR and 400 RS variants across the 2011-2023 model range.
- A front differential capacity of 4.8 liters is a relatively substantial fill volume, consistent with a housing designed for heavier-duty or agricultural use rather than a compact passenger vehicle differential.
- The Invictus K600 AR, available from 2015, carries a front differential capacity of 5.5 liters, the largest front differential fill volume across all listed Invictus configurations.
- Despite sharing the K600 designation and the same model year range starting in 2015, the AR and RS variants differ in front differential capacity. The K600 AR holds 5.5 liters while the K600 RS holds 4.0 liters, a difference of 1.5 liters that reflects a meaningful distinction in differential housing size or design between the two trim levels.
- All six configurations list front differential fluid capacity under normal use conditions, meaning the specified volumes apply to standard operating environments rather than severe-duty cycles.
- The 300 and 400 series variants share the same 4.8-liter front differential capacity despite the difference in engine or power designation, suggesting a common front axle assembly across those four configurations.
