Land Rover Discovery L550 Front Windscreen Wiper Arm Right O/S FK72-17526-AA

Land Rover Discovery L550 Front Windscreen Wiper Arm Right O/S is an original component from the Wiper arms group, designed for operation on the driver's side in right-hand drive vehicles. Designed by the vehicle manufacturer, it ensures the correct geometry of the blade pressure against the windscreen, stable operation throughout the full range of motion, and predictable performance in difficult weather conditions.

Purpose and fitment

The arm is dedicated to the front windscreen on the right side, which guarantees compatibility with the factory wiper system in the Land Rover Discovery L550. The properly selected length, operating angle, and mounting method allow for seamless cooperation with the original wiper mechanism and blade, without the need to modify other components. Thanks to a design compliant with the manufacturer's standard, the component maintains the correct resting position, does not collide with the bonnet or windscreen seals, and ensures even cleaning of the driver's field of vision.

Construction and performance parameters

The wiper arm has been designed as a rigid yet sufficiently flexible structure that transfers force from the drive mechanism to the blade, minimizing vibration and noise. The precisely manufactured mounting socket ensures stable seating on the drive axle, which limits the risk of operational play during use. The arm profile is optimized for aerodynamics, which helps reduce blade lift at higher speeds and improves the comfort of the wiper system's operation. The applied design solutions promote even blade pressure along the entire length, which translates into a clear, clean windscreen in rain and slush.

Condition, origin, and benefits of choosing a used part

The component comes from vehicle dismantling and is offered as a used OEM part, which means it retains factory fitment parameters and compatibility with the bodywork and wiper mechanism. Choosing an original reclaimed arm allows you to maintain the technical consistency of the vehicle while reducing service costs compared to new replacements. For many users, a significant advantage is also the ability to maintain a uniform appearance with the other elements of the wiper system, without differences in shape or arm lines that may occur with non-original solutions.

Why it is worth using a dedicated wiper arm

Using the correct arm on the right side of the windscreen has a direct impact on driving safety, as it is responsible for effectively cleaning the driver's key field of vision. Proper fitment to the drive axle and windscreen:

• ensures stable, predictable blade movement across the windscreen,
• reduces the phenomenon of "skipping" and uncleared zones,
• reduces the load on the wiper drive mechanism,
• facilitates service and periodic replacement of the blades themselves. By choosing an original wiper arm for Land Rover Discovery L550, you gain the certainty of compliance with the vehicle's factory specification and predictable system behavior in daily operation. If you are planning a comprehensive repair or upgrade of the windscreen visibility zone in your Land Rover and need other elements from the same group, such as additional arms, mounts, or compatible blade holders, check the available parts in the Land Rover Wiper arms category. To better understand the advantages of using original reclaimed components and the possibilities of reducing service costs while maintaining an appropriate level of safety, it is worth reading the article Brake calipers under the microscope: How to effectively reduce brake system repair costs by choosing proven reclaimed parts, which discusses a practical approach to selecting used components.
