Timing Chain for Audi A4: Aluminium Alloy
This timing chain for the Audi A4 is specified around aluminium alloy, 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 documentation that arrived after the container shipped. Both are specification problems, and both are preventable.

Material options
- Anodised Aluminium — specified where the part sits close to a heat source
- PU Leather — used when the finish has to hold a coating
- Forged Aluminium — chosen where wear resistance comes first
- Magnesium Alloy — the cost-effective default for volume programmes

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.
Where it is used
The specification above is the one most often ordered for long-distance touring. Related applications include motocross, track days, weekend riding, mining sites, construction sites.
Quality and packing
- In-line inspection with AQL 2.5 sampling on every lot.
- Dimensional report issued against the approved drawing.
- Carton marking and barcode to your specification.
- Golden sample retained at the factory as the reorder reference.
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.
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 3000 pieces per line.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 3 days once you have seen the first piece.
