NISSAN 87552-VD01H Inner Left Seat Rail Assembly

This genuine Nissan (OEM: 87552-VD01H) inner left seat rail (RAIL ASSY-INR L) is a premium quality, original component responsible for securing the seat and ensuring its precise longitudinal adjustment. The inner seat rail plays a crucial role in seat stability, providing optimal and safe positioning for the driver or passenger within the vehicle.

Technical Features and Specifications:

• Manufacturer: NISSAN (Original Equipment Manufacturer)
• Part Number (SKU): 87552-VD01H
• Fitting Position: Front left seat, inner side (center console side)
• Material: High-tensile, hardened steel alloy for maximum structural integrity
• Surface Protection: Special corrosion- and wear-resistant coating that minimizes friction and prevents rust
• Mechanism: Precision roller and locking system for stepless or fine-increment adjustment

Function and Importance:

The seat rail not only provides a comfort function but is also a critical passive safety element. In the event of a collision, the seat track must withstand immense shear and tensile forces to keep the seat firmly anchored to the body structure, thereby supporting the effective operation of the seat belt and airbag systems.

Typical Signs of Wear or Failure:

• Difficult, sticking, or uneven sliding of the seat during adjustment.
• Metallic squeaking or clicking noises during seat positioning or while driving.
• Noticeable free play (instability or rocking of the seat under acceleration or braking).
• Locking mechanism failure, where the seat fails to latch securely into the selected position.
• Visible mechanical deformation or corrosion along the rail's running surface.
