Coil Spring for Dodge Ram: PU Leather
This coil spring for the Dodge Ram is specified around pu leather, 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 a specification nobody had written down, or reorders that did not match the approved sample. Both are specification problems, and both are preventable.
