Vortec MAX is a premium kit available on high-end trims for both Sierra and Silverado. All MAX models feature an upgraded performance chassis, but you can order this chassis upgrade separately without the MAX engine. Because it’s an add-on, you can’t say, “If you have this feature, you have a MAX engine.”
Ultimately, the best method to tell if you’re using the MAX engine is to utilize a VIN decoder. Some MAX engines have red “MAX” lettering on the hood. Alternatively, you can check the engine block plate to see the car’s engine code, but decoding the VIN is one of the best methods.
