Check fitment for your specific vehicle (model, year, engine) before ordering.

What Is This Part?
This pin is a small mechanical fitting within the window regulator assembly. The regulator is the mechanism that raises and lowers the door glass, working with the window motor and the associated guides. The pin forms part of that mechanical arrangement alongside the regulator roller and guide components. Its condition should be checked during window-lifter repairs, particularly where wear or damage is found around the pin and its seating.

What Does This Part Do?

Forms part of the regulator mechanism: Provides a mechanical connection within the window-lifter assembly.
Works with neighbouring components: Functions alongside the regulator roller and guides as the mechanism moves the glass.
Supports a targeted repair: Allows a damaged pin to be renewed when inspection shows the surrounding mechanism remains serviceable.

Why Replace This Part?
Replacement is appropriate when the existing pin is worn, bent, damaged or no longer seats correctly in the mechanism. Wear at a mechanical connection can introduce unwanted play, so the condition of the pin and the parts it engages should be assessed together.

Replacing the pin alone will not resolve every window fault. Check the roller, guides, regulator and motor before deciding which components need attention. If the pin remains undamaged and fits correctly, window-system symptoms alone are not a reason to replace it.

When to Replace This Part?

Visible damage: The pin is bent, broken or damaged during removal.
Wear at the connection: Inspection identifies wear on the pin or excessive play where it fits.
Poor seating: The pin cannot be correctly located or retained; inspect its mating components as well.
Window movement problems: Uneven travel, clicking or glass that will not move warrants inspection of the complete window system before selecting repair parts.

Where Is This Part Fitted?
Location: Within the door, as part of the mechanical window-lifter assembly alongside the regulator roller and guide components.

Product Information

Window Lifting Rail.
Restore smooth and reliable window operation with this OE Match Window Lifting Rail. Designed for compatible vehicle applications, the lifting rail forms part of the door window regulator mechanism and helps support, guide, and control the movement of the window glass as it is raised or lowered.

Fits:

Porsche 356B 1959-63 (COUPE)
Porsche 356C 1963-65 (COUPE)

Diagram Ref No 23

The window lifting mechanism relies on correctly aligned rails, guides, regulator components, and mounting points to move the glass smoothly through the door frame. A worn, bent, corroded, or damaged lifting rail can interfere with this movement, causing the window to become stiff, uneven, noisy, or difficult to operate.

What This Product Does:

Forms part of the window lifting and regulator mechanism.
Helps support the window glass during operation.
Guides the glass as the window is raised and lowered.
Helps maintain correct window alignment within the door.
Supports smooth and controlled window movement.
Helps prevent excessive glass movement or tilting.
Works with the associated regulator, guides, and mounting components.
Helps the window close correctly against its seals.
Replaces a worn, bent, corroded, or damaged lifting rail.
Provides an OE-style replacement for compatible vehicle applications.

Symptoms Of Wear Or Failure:

Window glass tilting while being raised or lowered.
Uneven or jerky window movement.
Window becoming difficult to raise or lower.
Excessive resistance when operating the window.
Scraping, grinding, clicking, or rattling noises inside the door.
Window glass dropping or becoming loose within the mechanism.
Window failing to close fully.
Poor alignment between the glass and window seals.
Excessive movement of the glass when partially open.
Visible corrosion, bending, distortion, or damage to the lifting rail.
Damage discovered while repairing the window regulator mechanism.

Why Replacement Matters:

The lifting rail plays an important role in keeping the window glass correctly supported and aligned. If the rail becomes bent, worn, corroded, or damaged, the glass may no longer travel through the door smoothly.
Continued operation with a faulty rail can place additional strain on the window regulator and associated components. Increased resistance or misalignment may accelerate regulator wear and can potentially cause further damage to guides, rollers, cables, mounting points, or the glass itself.
Incorrect window alignment can also prevent the glass from sealing properly when closed. This may contribute to increased wind noise, water ingress, rattling, or difficulty securing the vehicle.
Replacing a worn or damaged component with the correct OE Match Window Lifting Rail helps restore smooth window movement, correct glass alignment, reliable closure, and dependable operation of the window lifting mechanism.

FAQs

Is the rail side-specific?
Yes. Reference 64454204521 is for the left side and 64454204621 is for the right side.
What should be inspected during installation?
Check the regulator, glass guides, clamps and related fittings for wear, corrosion or incorrect alignment.
Why does the window glass tilt?
A damaged lifting rail, loose glass mounting or wear elsewhere in the regulator mechanism can allow uneven movement.
