This is the genuine Porsche conical spring (part number 64454247300) used in the window winder / crank handle assembly on Porsche 356 model doors. It’s the factory-specified spring for restoring original feel and return action.
Fits:
Porsche 356 1950 - 1965 all models
Diagram ref no 76
When installed in the window winder or crank handle, this conical spring provides the return tension that snaps the crank back to rest when rotated. It ensures smooth, consistent motion and proper alignment of the winding lever.
With age, springs can weaken, lose shape, or corrode, resulting in a sloppy crank feel, misalignment, or poor return. A genuine Porsche spring restores the correct tension, alignment, and reliable operation of the crank handle system.

When installed in the window winder or crank handle, this conical spring provides the return tension that snaps the crank back to rest when rotated. It ensures smooth, consistent motion and proper alignment of the winding lever.
Over time, the factory spring can weaken, lose its shape, or corrode—leading to sloppiness in the crank handle, poor return action, or misalignment. A fresh OE Match replacement restores firm tension, precise motion, and long-term durability.

Porsche Interior Door Panels | Premium Craftsmanship & Authentic Fitment
Interior door panels are an essential part of your Porsche’s cabin design — blending style, comfort, and function. They provide structure to the door assembly, house handles and switches, and contribute to sound insulation and aesthetic refinement. Over time, these panels can wear, fade, or warp, making replacement the key to restoring your Porsche’s luxury interior.
At Design911, we supply high-quality interior door panels designed to meet or surpass original specifications for precision and finish. Constructed from premium materials including leather, Alcantara, and durable composites, our panels ensure perfect alignment, refined textures, and a seamless match to your Porsche’s interior design.
Whether you’re restoring a classic 911, refurbishing a Cayman, or upgrading a modern model, our door panels deliver performance, authenticity, and timeless appeal.
What Do Interior Door Panels Do?
Door panels are more than decorative — they serve both practical and comfort-enhancing roles inside your Porsche.
Core Functions:
- Provide structure and housing for handles, switches, and window controls.
- Improve acoustic insulation and cabin comfort.
- Enhance aesthetic harmony throughout the interior.
- Protect wiring, window mechanisms, and locking systems.
- Support airbag deployment areas (where applicable).
A well-maintained door panel ensures a quiet, comfortable, and visually cohesive driving experience.
Why Do Door Panels Wear or Fail?
Even with Porsche’s craftsmanship, interior door panels experience wear and stress over years of use.
Common Causes of Damage Include:
- Fading and cracking from UV exposure.
- Delamination of leather, vinyl, or fabric surfaces.
- Broken clips or warped substrates causing misalignment.
- Moisture ingress leading to swelling or adhesive failure.
- Scuffs, tears, and general wear from regular use.
When damaged, panels can creak, loosen, or spoil the cabin’s luxury finish — making replacement essential for both comfort and value.
