Construction and technical characteristics

The cylinder is part of the hydraulic system responsible for assisting the opening of the tailgate. The design provided by the vehicle manufacturer guarantees:

• appropriately selected lifting force matched to the weight of the tailgate,
• controlled movement speed across the full range of opening and closing,
• compatibility with factory mounting points in the body and tailgate,
• compatibility with the original tailgate control system.

By maintaining factory geometry and operating parameters, this component allows for restoring stable tailgate operation without the need for using aftermarket solutions with uncertain properties.

Condition, fitment, and installation

The offered cylinder is a used part, sourced from dismantling, which allows for an economical repair while maintaining the original manufacturer's specifications. The component is intended for installation in the rear of the vehicle, in place of the factory cylinder, using existing mounting points.

When selecting a component, it is worth paying attention to compliance with manufacturer markings and reference numbers – the product has an assigned OEM part number and interchangeable numbers, which facilitates verification of compatibility with a specific version of the Mercedes ML W164. This allows for precise matching of the component to a given vehicle unit.
