BMW Rear Door Brake (525i 740i M5) - Genuine BMW 51228168090

Product Information

A door stop (also called a door check or door check strap) is a component inside the door assembly that limits how far a car door can open and holds it in certain positions. It prevents the door from swinging too wide, protects hinges from stress, and helps keep the door steady when partially open.

• Door swings freely or too far, indicating the stop is broken or worn.
• Clicking, popping, or grinding noises when opening or closing the door.
• Difficulty keeping the door open, as the stop no longer holds it in place.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
