Racing Crankshaft Components Specification Example for Courier Fleets: Off-Road Version
Racing Crankshaft Components Specification Example for Courier Fleets: Off-Road Version
This is a worked specification for racing crankshaft components in a off-road 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 off-road version version exists because the duty cycle on courier fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually packing that arrived crushed at the port.

How the example is built up
- Start from the duty cycle, not from the catalogue photograph.
- Fix the base material in writing — Carbon Fibre 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
- powder coating
- precision stamping
- anodising
- heat treatment
- ultrasonic cleaning
- surface grinding
Where this example applies
Programmes that run off-road version most often specify this build for courier fleets. Related applications include emergency vehicles, courier fleets, off-road bikes, dealership service, utility trailers.
Checks before packing
- Dimensional report against the approved drawing.
- AQL 2.5 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
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 200 pieces per line.
What is the minimum order quantity?
The standard MOQ is 200 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
