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.

Set of 2 (Left & Right) assemblies with fixings
Fits:
Porsche 356 pre A / 356 A to 1959
Replica of the optional vent windows that were available as an accessory for the Porsche 356 pre A and A coupe models. This rare option combined a supplemental window glass mounted in two chrome brackets. When fixed at the front of the door window these assemblies reduced the draft in the cabin with the window lowered.
The upper pivot is mounted to the outside of the window frame at the front, the base is attached with bolts to the door.
These concours quality replicas have Duro marked glass within thick chromed brass frame pieces. The top pivot bracket, rubber seal, white acrylic spacers and required fixings are included in the kit.
Fitting guides are now shipped with the option vent windows. These are affixed to the doors and act as a template to aid correct positioning of the mounting holes.
