Purpose and function of the BMW X5 X6 E70 E71 gas spring

The presented gas spring is responsible for the controlled movement of the tailgate in BMW X-series SUVs, working in the lifting and stabilization axis. As a component from the Tailgate and rear parts category, it works in conjunction with hinges, the lock, and any potential electric drive, creating a cohesive system responsible for convenient access to the luggage compartment.

Selecting the correct gas spring for the BMW X5 E70 or X6 E71 is crucial for:

• proper balancing of the heavy tailgate,
• reducing the load on hinges and mounts,
• safely holding the tailgate in the open position during loading.

Construction and technical characteristics

The gas spring used in this generation of BMW X5 and X6 is constructed as a precision component that guides movement in one direction, with a specifically calibrated force characteristic. This ensures the tailgate opens smoothly, without sudden jerks, and its closing remains predictable and controlled.

The original BMW design ensures:

• compatibility with factory mounting points on the body and tailgate,
• the correct working length and piston stroke,
• force parameters matched to the weight of the tailgate in X5 E70 and X6 E71 models.

Benefits of using an original BMW gas spring

Using a gas spring dedicated to specific BMW X-series models allows you to maintain the factory operating characteristics of the tailgate. This means:

• reliable cooperation with other tailgate system components – hinges, lock, and any control systems,
• no need for mounting modifications or interference with the bodywork,
• preservation of the opening and closing geometry intended by the manufacturer.

For components in the Tailgate and rear parts group, it is particularly important that the gas spring does not cause excessive structural load while providing sufficient support for the tailgate – the original BMW solution was designed with exactly this assumption.

Product condition and service application

The offered gas spring is a used component, making it an attractive cost-effective alternative while maintaining BMW factory specifications. This type of part is suitable both for standard replacement of a worn-out gas spring and for post-accident repairs of the rear body section, where it is necessary to restore full tailgate functionality.

Selecting the correct gas spring for a specific version of the BMW X5 E70 or X6 E71 should take into account the manufacturer's markings and reference numbers – their compatibility guarantees the proper operation of the entire tailgate lifting system.
