Vehicle Application and Function

The presented gas strut is a component of the rear hatch lifting system for BMW X5 E70 and BMW X6 E71, belonging to the Hinges, Locks, and Other Hood Parts group. It is responsible for assisting the movement of the tailgate, relieving stress on hinges and mountings, and stabilizing the hatch’s position in its extreme points. A properly selected strut reduces the risk of the hatch closing spontaneously, which enhances user safety and protects the bodywork from mechanical damage.

Construction and BMW Fitment

The strut was designed by BMW as an original part, with appropriately selected gas pressure and stroke length to work with the weight and geometry of the tailgate in the mentioned models. The design incorporates factory mounting points, allowing for installation without modifications, while maintaining the original operating geometry of the hinges and lock. This ensures that after replacement, the predictable opening and closing characteristics, as intended by the vehicle manufacturer, are preserved.

Performance Characteristics and Benefits

• Assists in lifting the tailgate, reducing user effort.
• Stabilizes the hatch in the open position, minimizing the risk of sudden closure.
• Protects hinges and the lock from excessive dynamic loads.
• Factory-matched to the body geometry of BMW X5 E70 and X6 E71.
• Allows for replacement of a worn part without altering the body structure.

Thanks to these features, the strut is a functional service solution for issues with holding the hatch in the upper position, stiff opening, or uneven operation of the lifting system.

Part Condition and Service Application

The offered part is a used item, sourced from disassembly, allowing for economical repair while maintaining the original manufacturer’s specifications. This type of component is particularly useful in situations where the existing strut has lost pressure, causes the hatch to sag, or requires preventative replacement in conjunction with the opposite strut. Using an original solution minimizes the risk of parameter mismatch compared to random aftermarket alternatives.
