Aluminum Alloy Wheel Hub Specification Example for Dealership Service: Racing Spec
Aluminum Alloy Wheel Hub Specification Example for Dealership Service: Racing Spec
This is a worked specification for aluminum alloy wheel hub in a racing spec programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The racing spec version exists because the duty cycle on dealership service is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually warranty claims traced back to a single lot.

Where this example applies
Programmes that run racing spec most often specify this build for dealership service. Related applications include boat trailers, dealership service, scooter fleets, courier fleets, export programmes.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 4.0 sampling on the finished lot.
- Finish inspection under agreed lighting.
- Carton drop test on the first lot of a new packing specification.
Questions buyers ask
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.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
