Dual Mass Flywheel for GMC Sierra: Bronze
This dual mass flywheel for the GMC Sierra is specified around bronze, 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 a specification nobody had written down. Both are specification problems, and both are preventable.
