Air Duct for GMC Sierra: Brass
This air duct for the GMC Sierra is specified around brass, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is lead time that slipped twice before bulk started, or packing that arrived crushed at the port. Both are specification problems, and both are preventable.
