Air spring numbers and cross-references

Updated 2026-10-14

Quote an air spring from the number molded on the bag. If you also have a cross-reference, send both and say which one is stamped on the part Carmally should match.

Rolling-lobe and bellows bags are labeled many ways. Carmally keeps one canonical row when two buyer codes point at the same configuration, so the site does not publish competing URLs.

Read the number on the bag

The molded or stickered code on the rubber is the primary quote key. Cross-reference charts help buyers search; they do not replace the number on the part you are replacing.

How dual codes are published

When two common search codes map to one configuration, Carmally keeps a single page and lists both codes. W01-358-9781 and 1R12-603 share one canonical row. Your purchase order should still name the code your buyer uses.

RFQ extras that help

FAQ

Are W01-358-9781 and 1R12-603 the same catalog row?

Yes — one canonical page so the two search strings do not fight. Confirm the code on your bag before you order.

Do you publish a year-make-model air spring chart?

No. Send the number on the bag or the measurements if the number is gone.
