Purpose and function of the upper lock

The presented lock has been designed specifically for installation in the rear left part of the vehicle, in the upper door area. It is responsible for:

• stable guidance of the door leaf during closing and opening,
• secure locking in the closed position,
• maintaining the correct door geometry for high-roof bodies.

Thanks to its fitment for the specific high-roof body model, the lock works in conjunction with other locking elements, reducing play and unwanted vibrations while driving.

Construction and fitment for Ford Transit Custom

The upper rear door lock has been constructed as a component that works with factory Ford hinges and guides. Its shape, mounting points, and latch geometry are adapted to the rear left side of the vehicle, which facilitates installation and subsequent adjustment.

Its original Ford origin helps maintain consistency with the factory locking system and minimizes the risk of door closing issues after replacement. This solution is particularly beneficial for heavily used commercial vehicles, where the precision of the locks has a direct impact on user comfort and cargo protection.

Condition of the component and benefits of using a used part

The offered lock comes from the used original parts segment, which allows for a reasonable cost while maintaining a construction consistent with Ford's factory standards. In practice, this means:

• preservation of original geometry and mounting points,
• compatibility with the existing door mechanism,
• the possibility of economical repair without the need for replacements with uncertain fitment.

This is a good solution for post-accident repairs, replacing worn locking elements, or restoring full functionality to the rear doors in fleet vehicles.

Application in the rear left body section

Its placement in the rear left part of the vehicle means the lock operates in a critical body area, particularly exposed to operational loads. A properly functioning component:

• facilitates daily operation of the cargo space,
• reduces the risk of the door not closing properly and the generation of noise,
• supports the sealing of the rear body section.

Thanks to this, the vehicle maintains functionality in accordance with the manufacturer's specifications, which is important both in goods transport and specialized conversions.
