Purpose and vehicle placement

The gas strut is designed to work in the rear of the vehicle, where it is responsible for supporting and guiding the tailgate. It can be used on both the right and left sides, which facilitates selection when replacing a single component or a pair. Such a solution allows for maintaining consistent operating parameters on both sides of the tailgate and reduces the risk of misalignment.

Technical and functional characteristics

The component belongs to the Gas springs, locks, hinges and other parts group, which means it has been designed to handle dynamic loads associated with frequent opening and closing of the tailgate. The design of the gas strut ensures:

• controlled movement of the tailgate throughout the full range of opening,
• proper support in the open position,
• reduction of sudden impacts when closing,
• stable cooperation with the hinges and the tailgate lock. Thanks to its factory origin from the Ford brand, the correct mounting points and operating geometry are maintained, which translates into predictable tailgate behavior in all conditions.

Benefits of using an original gas strut

Using an original gas strut in a Ford Transit Custom allows for maintaining compliance with the factory design specifications of the body. Key advantages include:

• secure fit to the body – no need to fabricate mounts or use adapters,
• consistent operation on the left and right sides of the tailgate,
• maintaining the comfort of operating the tailgate during daily use of a delivery vehicle,
• reducing the risk of overloading the hinges and lock thanks to the properly selected characteristics of the gas strut. This solution is particularly beneficial for vehicles working intensively – in deliveries, mobile service, or local transport – where the tailgate is opened multiple times throughout the day.

Component condition and service application

The offered gas strut comes from dismantling and is intended for service applications as a spare part. This type of component allows for restoring the proper operation of the tailgate in a situation where the existing gas strut loses pressure, does not hold the tailgate up, or causes uneven opening. Replacing both sides simultaneously is recommended if you want consistent operation and predictable tailgate behavior in the long term.

Part selection and additional information

When selecting a gas strut for a Ford Transit Custom, it is worth paying attention to compliance with the manufacturer's markings and placement on the vehicle to avoid installation problems. If necessary, you can use markings such as SKU, OEM part number, or interchangeable numbers, which facilitate the identification of the correct variant. If you are planning a comprehensive repair or modernization of the rear body area in your Ford and need other components from the same group, such as additional gas springs, tailgate locks, or hinges, check the available parts in the Gas springs, locks, hinges and other parts Ford category. If you are considering the choice between a used original component and a cheap replacement, it is worth knowing the differences in durability and total operating costs – this is discussed in more detail in the article Cheap car part replacements – hidden defects and costs that workshops rarely talk about, which will help you make an informed service decision.
