* Body style: Both years are part of the same generation (GMT800), so body parts are largely interchangeable. However, minor trim differences might exist.
* Engine: Engine parts are generally interchangeable *within the same engine family*. If both trucks have the same engine (e.g., 4.8L, 5.3L, or 6.0L), parts will be compatible. Different engines will require different parts.
* Specific Options and Trim Levels: Some parts are specific to certain trim levels or optional equipment (like specific sound systems or interior features). While many parts are common, double-checking the part numbers is always recommended.
* Transmission: Transmission parts should generally be interchangeable if the transmissions are the same type.
* Suspension: Suspension parts are generally interchangeable, but minor variations might exist due to different packages or options.
In short: While many parts are compatible, always double-check the part numbers to ensure a proper fit. Using a reliable online parts catalog (like AutoZone, Advance Auto Parts, etc.) and entering the VINs of both trucks will give you the most accurate information. Comparing part numbers is crucial for avoiding compatibility issues.
