51 31 1 800 471 is the rear window seal of BMW E3 saloons with the narrow window trim: the 2500, 2800, 2.8 L and Bavaria, and the 3.0 S / 3.0 Si until they got the wider trim in 1973, in US and European versions. It replaced 51 31 1 809 989. BMW no longer makes it, and new old stock is almost impossible to find. We are making a new production run of this closed-frame seal in black EPDM rubber, reproduced from an original with the same profile: a channel for the glass, one for the body flange and a groove for the trim strip. Preorder it on its own or together with the US windscreen seal; if the run does not go ahead, you get a full refund.

Frequently asked questions
Which cars does it fit?
E3 saloons with the narrow window trim, US and European: the 2500, 2800, 2.8 L and Bavaria, and the 3.0 S / 3.0 Si until they got the wider trim in 1973. It replaced 51 31 1 809 989. Cars with the wider trim (later 3.0 S / 3.0 Si, 3.0 L, 3.3 L and 3.3 Li) use 51 31 1 828 234. Not sure? Email us your chassis number or a photo of your rear window trim before you order.
Is this an original BMW part?
No. It is a new reproduction by Replique labs, an independent manufacturer, made from original seals as reference. We are not affiliated with BMW AG; the part numbers only identify the application.
When do I pay, and what if the run does not go ahead?
You pay when you preorder. Production starts once enough preorders are in. If the run does not go ahead by 31 December 2026, we refund the full amount, shipping included, within 14 days.
Can I cancel my preorder?
Yes. Until we confirm the run you can cancel at any time by email for a full refund. Consumers in the EU can also withdraw within 14 days of delivery, as set out in our Terms of Sale.
When will the seals arrive?
Estimated delivery is spring 2027. We will email you when the run is confirmed and when your seals ship.
Why does the run need enough preorders?
A rubber seal needs its own tooling: an extrusion die for the profile and moulds for the corners. That cost only makes sense when it is shared across a batch.
Are the trim strips included?
No, only the rubber seal. Your original aluminium trim strips refit into the new seal.
Who should fit the seal?
We recommend an experienced auto glass fitter. The seal holds the glass in the body opening, so correct fitting matters.
Do you ship to the US and outside the EU?
Yes, worldwide with tracking. Outside the EU no EU VAT is charged; import duties and taxes in your country, if any, are paid on delivery.
I am a dealer or restorer. Can I order several seals?
Yes. As on all our parts, the price per piece drops as the quantity grows. For larger quantities, contact us.
