Steering Damper Specification Example for Municipal Fleets: Racing Spec

This is a worked specification for steering damper 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 municipal fleets 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

  1. Start from the duty cycle, not from the catalogue photograph.
  2. Fix the base material in writing — Chromed Steel, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Processes involved

  • anodising
  • shot blasting
  • laser cutting
  • assembly line testing
  • electroplating
  • cold forging

Where this example applies

Programmes that run racing spec most often specify this build for municipal fleets. Related applications include workshop replacements, racing teams, export programmes, agricultural trailers, off-road bikes.

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 SAE J431-compliant build instead of a fresh interpretation.

What testing is included?

Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.

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.

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.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
