Product Information
This Genuine BMW trunk lid lift support is a common wear item on higher mileage E60 models and is often the cause of a trunk lid that will not stay open or opens too aggressively.
The trunk lid lift support, also known as a trunk strut or trunk shock, is a gas charged cylinder that helps lift and support the trunk lid during opening. It makes the trunk easier to open, helps hold it securely in place, and prevents the lid from closing unexpectedly while loading or unloading.
Over time, the internal seal inside the lift support can wear out and lose pressure. When this happens, the trunk lid may feel heavier than normal, fail to stay open, or move too quickly when released. Corrosion, age, and repeated use can also affect smooth operation and create weak spots through the travel range.
Common failure symptoms include a trunk lid that will not stay open, a trunk that opens too quickly, weak or uneven support, internal pressure loss, corrosion, rust, or dead spots during operation.
Using a Genuine BMW replacement lift support helps ensure proper fitment, correct opening behavior, and long-term compatibility with the vehicle’s original trunk mechanism.
