Purpose and function of the tension spring

The rear tension spring in the BMW G20 model is responsible for the controlled opening and closing of the trunk lid, as well as keeping it in a stable position once lifted. This component works in conjunction with the hinges and other mechanism parts, reducing the load on the mounts and improving the ergonomics of using the trunk.

Thanks to its dedicated placement in the rear body section, the spring is matched to the geometry of the BMW G20 trunk lid, which translates into proper force characteristics and smooth movement. Using an original solution allows for maintaining the factory performance parameters of the entire system.

Benefits of using an original BMW spring

Choosing an original rear tension spring for the BMW G20 is primarily an investment in compatibility and predictable trunk lid behavior. The component has been designed for a specific model, ensuring that it:

• provides appropriately selected assistance force for opening and closing the lid,
• reduces the risk of excessive load on hinges and mounts,
• maintains consistency with the factory construction of the rear body section,
• allows for maintaining repeatable, stable operation of the mechanism in daily use.

This used component from the Tailgates and rear parts group is a reasonable solution for post-accident repairs, replacing worn-out components, or restoring full functionality to the rear zone of the vehicle without the need to resort to replacements with uncertain parameters.

Condition, installation, and vehicle fitment

The tension spring comes from disassembly and is offered as a used part, which allows for economical repair while maintaining the original BMW specification. The component is intended for installation in the rear part of the vehicle, within the trunk lid mechanism, using the factory mounting points.

When selecting the component, it is worth paying attention to compatibility with the specific BMW G20 body version and matching it to the existing hinge and mount system. A properly selected tension spring helps eliminate problems such as the lid dropping, uneven opening, or excessive resistance when lifting the trunk lid.

Application in rear body repairs

The component is perfect for:

• repairs after collisions involving the rear of the vehicle,
• replacing a worn or weakened trunk lid spring,
• comprehensive regeneration of the lid opening and support mechanism,
• restoring full trunk functionality in the BMW G20.

Using an original tension spring allows you to maintain the structural integrity of the rear body section, which is important for both user comfort and the durability of the entire system.
