Aftermarket Engine Brackets Specification Example for Long-Haul Trucks: Low Maintenance Version

This is a worked specification for aftermarket engine brackets in a low maintenance 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 low maintenance version 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 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 — Anodised Aluminium, 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.

Where this example applies

Programmes that run low maintenance version most often specify this build for long-haul trucks. Related applications include fleet maintenance, utility trailers, long-haul trucks, passenger cars, city buses.

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

Can the specification be held on file?

Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the CCC-compliant build instead of a fresh interpretation.

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.

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 7 working days, and each revision round adds about 5 days once you have seen the first piece.

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