Purpose and function of the lock

The presented lock is dedicated to the rear right side of the vehicle, ensuring it works precisely with the cargo door structure of the Ford Transit Custom. It is responsible for the mechanical locking of the door wing, correct positioning of the door relative to the body, and keeping it stably in the closed position while driving. A properly selected lock reduces the risk of play, rattling, and leaks, which translates into more comfortable and quieter operation of the cargo area.

Construction and fitment for Ford Transit Custom

As a Ford brand component, the lock has been designed for factory-fitment to the rear door structure. The mounting holes, body geometry, and the way it interacts with the rods and handle are consistent with the solutions used in this model, which facilitates installation and minimizes the need for additional modifications. The vehicle placement specified as rear – right side allows for clear identification of the correct installation point and avoids mistakes when selecting parts.

Benefits of using an original lock

Using an original rear right door lock in a Ford Transit Custom provides a number of practical benefits:

• maintaining factory door closing geometry and proper seal contact,
• consistent cooperation with the existing opening mechanism from both the outside and inside,
• reducing the risk of accidental door opening while driving,
• easier diagnostics and service in the future due to compliance with manufacturer solutions.

This solution is particularly important in vehicles used intensively in local transport and distribution, where frequent opening and closing of cargo doors requires a reliable, well-fitted locking mechanism.

Characteristics of the used part

The offered lock comes from the used original parts segment, which allows for combining a favorable purchase cost with maintaining the structural parameters provided by the vehicle manufacturer. This type of component is a good choice for maintenance repairs when the priority is assembly compatibility while optimizing the service budget for a fleet or a single vehicle.

Selection and additional technical information

When selecting a rear right door lock, it is worth paying attention to compatibility with the specific body version and door configuration of a given Ford Transit Custom unit. Manufacturer markings, catalog numbers, and information about the placement on the vehicle can be helpful, as they facilitate clear identification of the part and reduce the risk of purchasing an incompatible item.
