Vehicle Speedometer Tachometer Specification Example for Long-Haul Trucks: Reinforced Build
Vehicle Speedometer Tachometer Specification Example for Long-Haul Trucks: Reinforced Build
This is a worked specification for vehicle speedometer tachometer in a reinforced build 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 reinforced build version exists because the duty cycle on long-haul trucks is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Neoprene, 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
- electroplating
- die casting
- CNC machining
- precision stamping
- injection moulding
- ultrasonic cleaning
Where this example applies
Programmes that run reinforced build most often specify this build for long-haul trucks. Related applications include aftermarket retail, delivery vans, utility trailers, fleet maintenance, municipal fleets.
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
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 2000 pieces per line.
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.
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.
What is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
