- Left-hand reference: 64454204521
- Right-hand reference: 64454204621
Symptoms of Fault
- Door glass tilts or binds during operation
- Window travel becomes uneven or requires assistance
- Clicking, scraping or grinding from inside the door

Why Replacement Matters
A worn, bent or corroded lifting rail can affect window alignment and place additional strain on the regulator and guides. Replacing the damaged component helps restore consistent movement and allows the glass to close correctly against its seals.
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.

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.
