Range Rover Sport L494 Rear Door Insulator Foam Right O/S DK62-20394-AC

Range Rover Sport L494 Rear Door Insulator Foam Right O/S is a precisely molded sound-deadening component designed for installation in the rear right door of this model. Thanks to its tailored geometry and the use of foam with appropriate acoustic properties, the insulator effectively reduces noise penetration from the outside and stabilizes the internal door panel components. It is a practical solution for users who want to maintain factory acoustic comfort and solid door construction in their Range Rover.

Purpose and function of the insulator

The presented foam insulator is a component from the Door Upholstery group, designed specifically for the rear right side of the vehicle body. Its task is to fill the space inside the door, improve vibration damping, and reduce air noise and the sounds of mechanism operation. The properly selected foam structure also helps in stabilizing wiring harnesses and mounting elements, which translates into quieter, less resonant operation of the entire door assembly.

Benefits of use in Range Rover Sport L494

Using a dedicated foam insulator in the rear right door of the Range Rover Sport L494 allows for maintaining the acoustic consistency of the interior and reducing unwanted sounds that appear while driving. Compared to universal sound-deadening materials, this tailored component provides:

• better adhesion to the door structure,
• more predictable behavior during temperature changes,
• preservation of the factory operating characteristics of the lock and window mechanism,
• easier removal and reinstallation of the upholstery during service. As a result, the vehicle's interior remains acoustically consistent, and the door operation is quieter and more orderly, which is particularly important in Range Rover class vehicles.

Installation characteristics

The insulator is designed for a specific location on the vehicle – the rear right door. This means that its shape, thickness, and edge lines are matched to the factory sheet metal stamping and internal mounts. In practice, this facilitates service work, as the element naturally "falls" into the intended place once correctly positioned, without the need for cutting or modification. Such a solution is particularly beneficial for accident repairs, upholstery replacement, or restoring original soundproofing after previous interference with the door structure. Maintaining the factory insulation layout also helps to keep predictable operating conditions for the electrical installation routed inside the door.

Component condition and service application

The offered foam insulator is a used component, which makes it an attractive service solution for Range Rover Sport L494 owners who want to optimize repair costs while maintaining the original construction. Such components are particularly useful in situations where the factory filling has been damaged or lost during upholstery removal, bodywork repairs, or mechanism replacement in the doors. Using an original, used insulator allows for restoring the soundproofing layout intended by the manufacturer, without the need to experiment with replacements of uncertain acoustic and dimensional parameters.

Expanding Range Rover door zone upgrades

Additional information and repair cost optimization

When planning service work, it is worth considering the impact of the quality of used components on the durability and comfort of vehicle operation. In many cases, used original parts allow for a favorable compromise between price and functionality, which is important not only for luxury SUVs but also for popular models of other brands.
