This is a plastic sliding clip used in the electric window mechanism of BMW 3 Series E36 (1990-1998), 5 Series E34, and Z3 models, manufactured with the quality of FEBI BILSTEIN (Germany). This part connects the metal arms of the window regulator to the rail under the glass; over time, it dries out, yellows, and breaks. It is vital for your window to operate smoothly and not come off the rail.
- Chronic Issue Resolution: The 99% cause of the window misalignment or jamming in E36s is the breakage of this part.
- OEM Quality Plastic: Made from hardened polyamide material, it does not crack during installation like cheap plastics.
- Perfect Fit: Fits snugly onto the window rail, eliminating any shaking and gaps in the glass.
- Wide Compatibility: Also used in the rear windows of E36, E34, E32, Z3, and some E90 models.

Frequently Asked Questions (FAQ)
How many should I buy for one door? There are **2 clips** in the window rail of one door. If one is broken, the other has likely worn out as well. It is best to replace both while you have the door trim removed.
Can the metal clip be removed? Typically, only the white plastic slider comes out of the Febi packages. You can remove the metal wire clip (fork) that secures the knob of the regulator from your old part and attach it to this one; they usually do not break.
What should I pay attention to during installation? The most important thing is **GREASE**. If you do not clean the rail where the slider will go and re-grease it, the new part will struggle due to friction and may burn out the window regulator motor or break the plastic again.
