BMW Bump Stop - Genuine BMW 51238123298

Product Information

The deck lid stop buffer is a small but important component mounted between the trunk lid (deck lid) and the vehicle body. Its primary function is to cushion and stabilize the deck lid when closed, preventing metal-to-metal contact, reducing noise, and ensuring proper alignment. Typically made from durable rubber or urethane, the stop buffer absorbs impact, minimizes vibrations, and helps maintain a secure, rattle-free fit of the trunk lid.

• Trunk lid rattling or vibration noises – caused by worn or missing buffers.
• Misaligned or uneven deck lid closure – indicates buffers are damaged or compressed.
• Visible cracks, hardening, or deterioration of rubber – reduces the buffer’s ability to absorb impact and protect the deck lid.

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.
