Window Regulator for Chevrolet Silverado: EPDM Rubber
This window regulator for the Chevrolet Silverado is specified around epdm rubber, 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 inconsistent hardness between lots, or a supplier who changed material without saying so. Both are specification problems, and both are preventable.
