Adjustable Rear Suspension Specification Example for Aftermarket Retail: Low Maintenance Version
Adjustable Rear Suspension Specification Example for Aftermarket Retail: Low Maintenance Version
This is a worked specification for adjustable rear suspension 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 aftermarket retail 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 — Polypropylene, 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
- cold forging
- die casting
- anodising
- precision stamping
- sintering
- CNC machining
Where this example applies
Programmes that run low maintenance version most often specify this build for aftermarket retail. Related applications include utility trailers, city buses, emergency vehicles, municipal fleets, rental motorcycles.
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 is the minimum order quantity?
The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the ISO 9001-compliant build instead of a fresh interpretation.
Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
