* Submodel: Parts interchangeability depends heavily on the specific submodel (e.g., 1500, 2500, 3500, extended cab, crew cab, etc.). A part from a 2001 Silverado 2500HD might not fit a 2002 Silverado 1500.
* Specific Part: Some parts are more interchangeable than others. Body panels are often similar, but drivetrain components (engine, transmission) might have more variations between years and models.
* Trim Level: While unlikely to be a major factor, some trim-specific parts (like interior pieces) might not be directly interchangeable.
* Changes Throughout the Year: There can even be minor differences in parts between early and late production runs within a single model year.
Therefore, while those years are generally considered compatible, always double-check part numbers to ensure compatibility before purchasing. Using a reputable parts website and specifying your exact Silverado's trim level and options will be crucial for accuracy.
