Used Knuckles / Spindles

A front door shell is the outer skin and frame of the door without the glass, regulator, trim panel, lock, or wiring. Body shops and rebuilders buy shells when the interior components of the original door are salvageable but the outer skin is too damaged to repair. Transferring the working internals into a clean shell is cheaper than buying a complete door assembly. Redline has 2 used Knuckles / Spindles listings from 1 verified sellers across 2 makes. Models from Mercedes Benz, Bmw are well stocked. Color matching matters here since the shell is the visible exterior panel. A shell in your factory color eliminates the need for paint, which typically runs $400 to $600 for a single door. Check the paint code on your door jamb sticker. Also confirm whether the shell includes the hinge mounting plates, door check strap bracket, and any reinforcement plates for side impact beams. Some sellers strip these items while others include them with the shell.
