Product Information

BMW Shock and Struts diagram for 735i, L7

A suspension strut cartridge is the internal shock-absorbing component housed within a strut assembly. It controls suspension movement by dampening the up-and-down motion of the springs, ensuring stability, comfort, and proper tire contact with the road. In some vehicles, the cartridge can be replaced separately without changing the entire strut housing.

• Excessive bouncing or poor ride comfort, as the cartridge can no longer dampen spring movement effectively.
• Nose-diving or body roll, especially during braking or cornering, due to weakened damping control.
• Fluid leaks or clunking noises, indicating internal seal failure or worn-out cartridge components.

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.
