BMW Trunk Shock - Tuff Support 51248103118

Product Information

The trunk lid lift support, also sometimes called a trunk strut or trunk shock, is a gas-charged cylinder that helps support and lift the trunk lid of a vehicle. Some trunk lift supports are also electric or hydraulic depending on the vehicle’s equipment. The trunk lift support assists the opening of the trunk or hatch, making it easier to open and sometimes opening it automatically. When you open the trunk, the lifting rod extends to push the lid open, ensuring it stays in place. Trunk lid supports remove the need to hold the trunk while loading and unloading and prevent it from slamming shut accidentally. Most European vehicles have a pair of supports, but occasionally there is just one. They are usually held onto the body and the trunk via posts and retaining clips, making them an easy DIY for most vehicle owners.

As a vehicle ages and the trunk support goes through hundreds of actuations, trunk lid lift supports will wear out and fail primarily due to the internal seal on the extending rod failing and losing pressure. When that happens, the trunk lid will feel heavier to open and slam shut unexpectedly. When replacing trunk lid supports that use a flat clip and post-mounting design, we recommend wearing some type of mechanic gloves since the retaining clips can be somewhat sharp and move unexpectedly when applying leverage with a screwdriver.

• Internal Leaks: If the gas piston is leaking internally, the trunk lid lift support won’t be able to leverage the trunk open
• Age/Corrosion/Rust: If the trunk lift supports are exposed to the elements or are very old, it could hinder smooth operation, causing dead spots in the operation
