Transfer Case for Geely Coolray: Carbon Steel
This transfer case for the Geely Coolray is specified around carbon 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 premature wear on the first batch, or documentation that arrived after the container shipped. Both are specification problems, and both are preventable.

Questions buyers ask
What testing is included?
Standard lots ship with dimensional and hardness reports. SGS documentation is issued with the shipment when your market requires it.
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.
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.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SGS-compliant build instead of a fresh interpretation.
Send the specification you are working to and we will confirm what we can match, what we would change and why.
