Mercedes W251 Tailgate Trunk Boot Lid Rear Damper Strut Spring A2519801264

Mercedes W251 Tailgate Trunk Boot Lid Rear Damper Strut Spring is an original lift system component for the rear hatch, designed for installation in the rear body section. It ensures stable operation of the tailgate, controlled movement damping, and convenient opening and closing of the luggage compartment. Thanks to its factory design tailored to the W251 series, this item from the Tailgates and rear parts category allows for maintaining the correct geometry of the tailgate and comfort in daily use.

Purpose and function in the vehicle

The presented telescopic strut operates in the rear zone of the vehicle, where it is responsible for supporting and damping the tailgate. Its tasks include:

• controlled lifting of the tailgate without sudden jerks,
• damping the movement during closing to reduce structural stress,
• maintaining the tailgate in a stable position after opening, which improves safety during use.

Due to its fitment for the Mercedes W251 series design, the strut works with the hinges and tailgate mounts in accordance with the manufacturer's specifications, which translates into predictable behavior of the entire system.

Construction and technical characteristics

The strut serves simultaneously as a guide telescope and a tailgate movement damper. The gas-telescopic construction enables smooth distribution of forces during opening and closing, while appropriately selected damping parameters limit impacts at the extreme positions. The element has been designed specifically for the W251 body, which means a matched working length, stroke, and mounting points.

The original origin from the Mercedes brand promotes maintaining the proper rigidity and resistance to operational loads in the rear part of the vehicle. This is particularly important in cars with an intensively used luggage compartment, where the tailgate is frequently opened and closed.

Benefits of using an original strut

Using a dedicated tailgate strut in a Mercedes W251 brings a number of practical benefits:

• Consistent tailgate system operation – properly selected force and damping parameters reduce the risk of overloading the hinges and sheet metal deformation.
• Better ergonomics – opening and closing the tailgate requires less effort, and the movement is more predictable.
• User safety – stable maintenance of the tailgate in the upper position limits the risk of it falling unexpectedly.
• Installation compatibility – factory mounting points facilitate replacement without the need for structural modifications.

Choosing an original element from this group allows for maintaining the operating characteristics intended by the vehicle manufacturer, which is especially important in the case of heavier, multi-component tailgates.

Condition and service application

The offered strut comes from the used parts segment, which makes it a cost-effective solution while maintaining the original design specification. This type of element is often chosen for:

• a decrease in the effectiveness of supporting the tailgate (the tailgate falls or does not lift all the way),
• uneven operation of the lifting system after replacing only one of the struts,
• post-accident repairs of the rear body section, when it is necessary to replace elements cooperating with the tailgate.

Thanks to the preservation of factory geometry and its purpose for the rear part of the vehicle, the strut fits well into standard service procedures for the Mercedes W251.
