Torque Converter for BMW X5: Zinc Plated Steel
This torque converter for the BMW X5 is specified around zinc plated steel, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is lead time that slipped twice before bulk started, or packing that arrived crushed at the port. Both are specification problems, and both are preventable.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.

Questions buyers ask
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.
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.
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.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
