Purpose and function of the gas strut

The tailgate gas strut in the Ford Transit Custom is responsible for stable opening and maintaining the tailgate in a set position. Thanks to the properly selected characteristics of the gas spring, this component:

• facilitates lifting the heavy tailgate,
• prevents the tailgate from dropping suddenly,
• improves the ergonomics of loading and unloading the cargo space,
• reduces the load transferred to the hinges and tailgate mounts.

The placement on the vehicle covers the rear part of the body, both the right and left side, which allows the gas strut to be used depending on the factory configuration of the vehicle.

Construction and technical properties

The gas strut operates based on a gas spring enclosed in a sealed housing, which ensures repeatable force characteristics throughout the entire range of operation. The design is adapted to the operating conditions typical for a commercial vehicle – frequent opening and closing of the tailgate, variable temperatures, and loads resulting from the weight of the tailgate.

Thanks to the factory fit for the Ford Transit Custom, the correct operating angles, stroke, and mounting points are maintained, which translates into proper tailgate movement geometry and no need for body modifications.

Benefits of using an original component

Using an original tailgate gas strut in the Ford Transit Custom allows for maintaining consistency with the factory vehicle specification. Key advantages include:

• secure support of the tailgate in the open position, reducing the risk of it falling on its own,
• comfortable operation of the trunk even with frequent use,
• compatibility with existing hinges, locks, and mounts,
• preservation of the tailgate operating characteristics intended by the manufacturer.

The component from this group is particularly important in commercial vehicles, where the cargo space is intensively used, and the efficient operation of the tailgate affects work speed and operator safety.

Characteristics of the used product

The offered gas strut comes from a used vehicle, which allows for an economical replacement of the component while maintaining the original installation specification. A used component of this type is often chosen as a reasonable compromise between cost and maintaining the factory fit to the body and tailgate mechanism.

Before installation, it is recommended to check the condition of the mounts on the vehicle and simultaneously assess the second gas strut (on the opposite side) to ensure symmetrical operation of the tailgate and even load distribution.

Fitment, identification, and selection

To correctly select a gas strut for a specific version of the Ford Transit Custom, it is worth paying attention to manufacturer markings, OEM part numbers, and interchangeable numbers visible in the technical specification. This allows avoiding installation problems and guarantees compliance with the factory vehicle configuration.

When selecting used components, expert tips regarding compatibility and interpretation of manufacturer markings can also be helpful – especially in the case of different body variants and production years.
