Window winder / crank handle conical spring. Porsche 356

Window winder / crank handle conical spring.
Sold each. Two springs are typically required per car (one for each door).

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.
