Steering Rack for Audi A4: Sintered Metal
This steering rack for the Audi A4 is specified around sintered metal, 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 premature wear on the first batch, or reorders that did not match the approved sample. Both are specification problems, and both are preventable.

Questions buyers ask
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
What testing is included?
Standard lots ship with dimensional and hardness reports. DOT documentation is issued with the shipment when your market requires it.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
