Aftermarket Engine Brackets Specification Example for Dealership Service: Upgraded Version
Aftermarket Engine Brackets Specification Example for Dealership Service: Upgraded Version
This is a worked specification for aftermarket engine brackets in a upgraded version 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 upgraded version 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 a supplier who changed material without saying so.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Ceramic Composite, in this example.
- List the dimensions that are actually controlled and the tolerance on each.
- Name the finish and what it has to survive.
- State the inspection level and who pays when a lot fails.

Processes involved
- sintering
- robot welding
- precision stamping
- electroplating
- gravity casting
- injection moulding
Where this example applies
Programmes that run upgraded version most often specify this build for dealership service. Related applications include camper conversions, three-wheelers, dealership service, boat trailers, assembly programmes.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 1.5 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
What testing is included?
Standard lots ship with dimensional and hardness reports. CCC documentation is issued with the shipment when your market requires it.
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
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 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.
