This is an engine-configuration application, not a blanket fitment claim for every GM truck in a listed year. Verify the block, oil-tower sealing layout and ventilation routing. AFM/DOD-equipped engines require a coordinated conversion.
- One non-AFM/DOD valley cover
- Valley cover mounting bolt set
- One valley cover gasket
- DOD oil-tower sealing gaskets
The cover closes the engine valley and uses the supplied tower seals in the compatible oil-passage layout.
A complete mechanical AFM/DOD conversion involves compatible lifters, camshaft and engine-control configuration. Plan those requirements separately from this cover package.
Identify the engine code and compare the original valley and oil-passage layout before installation. Seat the cover gasket and tower seals correctly.
Plan a compatible crankcase ventilation arrangement because this cover has no integrated PCV provision. Follow the engine service procedure and confirm the complete conversion configuration before operation.
