BMW Trailing Arm - Genuine BMW 33306871023

Product Information

A suspension trailing arm is a key component of a vehicle’s rear suspension system that connects the axle or wheel hub to the chassis. It helps control the rear wheel’s motion, keeping it aligned while allowing up-and-down movement over road surfaces. By maintaining stability and proper wheel alignment, the trailing arm contributes to smooth handling, consistent tire wear, and overall ride comfort.

• Clunking or knocking noises from the rear suspension, especially over bumps.
• Poor handling or instability, such as swaying or drifting during acceleration, braking, or cornering.
• Uneven tire wear, often caused by misaligned suspension geometry.

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.
