Regularly inspecting and replacing the hardware on critical portions of your vehicle's suspension, engine, and brake components is important for safety and stability, as well as maintaining the serviceability of your vehicle's common wear systems.

In certain applications on many European makes and models, bolts will be torque to yield and are specifically called out to be replaced once removed and not reused. When replacing a component, it's important to refer to the factory service procedures to determine an application fastener type, grade, installation torque values, and replacement recommendations

• Failure: Damaged hardware can fail under pressure, which can lead to engine damage, suspension component failure, and added wear
• Corrosion and rust: Over time, nuts and bolts can corrode or rust, which weakens them and increases the chance of failure
• Fatigue: Fasteners can fatigue due to exposure to debris, corrosion, water, and other contaminants. This fatigue can be caused by cyclic stress due to loss of initial pre-load

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.
