02How part numbers work on Chinese trucks

Chinese truck parts use four main numbering families — AZ for cabin and chassis assemblies, WG for chassis and driveline, VG for Weichai engine components, and numeric blocks such as 6156… for engine internals. The prefix tells you where the part sits on the truck, but the number alone does not tell you the engine or gearbox variant — that is why we ask for your VIN or engine number before shipping.

Equivalent parts are often sold under two or three different numbers, and workshops frequently quote the old number. If your number returns no result, it does not mean we cannot supply it: send the number and your truck model and we will cross-check it manually.

04How we make sure the right part is shipped

A wrong part is the most expensive mistake in parts sourcing — the part itself is useless, and the freight, the downtime and the re-order are all on you. This is what we do to prevent it.

  1. Photo confirmation before packingBefore anything is packed we photograph every part together with its part number, and send those photos to you.
  2. You approve, then we packPacking starts only after you confirm the photos show the parts you ordered. No confirmation, no shipment.
  3. Packing and dispatch photosOn the day your order leaves we photograph the packed cartons and the dispatched shipment, and send both to you.
  4. A packing list you can checkOrders often contain many different part numbers. Every carton is listed with its contents and the quantity of each part, so you can check the shipment against the paperwork when it arrives.
