Purpose and Compatibility with Mercedes SLK R171

The presented actuator set is specifically designed for the Vario roof system in the Mercedes SLK R171 model. It is responsible for the controlled lifting and folding of the roof panels, working in conjunction with the factory hydraulic pump and position sensors. This ensures the correct roof operation geometry is maintained, and the entire mechanism functions according to the manufacturer's specifications.

The set includes components installed on the right and left sides of the vehicle, which facilitates symmetrical servicing of the entire system. This approach minimizes the risk of roof operation discrepancies arising from uneven wear of individual actuators.

Set Construction and Vehicle Placement

The roof actuator set is intended for installation on the right and left sides of the body, in the area of the retractable roof guides and hinges. The placement of the components corresponds to the factory design of the Vario system, allowing for the use of original mounting points and existing hydraulic lines.

This solution ensures:

• maintenance of the roof's factory motion kinematics,
• consistent operation of both sides of the mechanism,
• easier future diagnostics and servicing.
