Purpose and function of the tailgate striker

The tailgate striker is responsible for mechanically locking the tailgate in the closed position. A properly functioning component:

• keeps the tailgate in a stable position while driving,
• prevents accidental opening of the trunk,
• reduces vibrations and unwanted noises from the rear of the vehicle,
• works in conjunction with the lock mechanism and the vehicle's system.

Thanks to a properly selected tailgate striker, the locking system operates in a predictable and repeatable manner, which translates into convenience of using the car.

Compatibility and fitment for Mercedes W164 / W251

Mercedes W164 W251 Boot Trunk Lid Tailgate Catch Striker Hook has been designed for use in the rear of the vehicle, in the tailgate area. The design based on the manufacturer's factory solutions allows for:

• maintaining the correct closing geometry of the tailgate,
• proper cooperation with the original lock and hinges,
• installation at the mounting points provided by the manufacturer.

Such fitment reduces the need for additional modifications and facilitates service in workshop conditions or during DIY replacement.

Characteristics of the used component

The offered striker comes from the Locks and Latches category and is a used part. This means it was previously used in a vehicle but can still perform its function after proper installation. In the case of this type of component, it is important to:

• check the mechanical condition before installation,
• verify the smoothness of moving parts,
• ensure correct alignment with the latch in the tailgate.

A used tailgate striker is a reasonable cost-effective solution while maintaining the functionality required for daily vehicle operation.

Benefits of using an original tailgate striker

Using a striker from the same design group as Mercedes factory solutions allows for maintaining the consistency of the rear body locking system. The most important advantages include:

• factory fit for the tailgate – compliance with the geometry intended by the manufacturer,
• stable locking – reduction of play and rattling in the trunk area,
• repeatable mechanism operation – predictable opening and closing of the tailgate.

For the user, this means more comfortable use of the trunk and a lower risk of problems with closing the tailgate.
