OEM GM Door Sills

What Are Door Sills and What Do They Do?

Door sills are the protective strips located at the bottom of your vehicle's door frames. They prevent dirt, moisture, and other elements from entering the cabin when you open and close the door. Door sills also add a touch of style to your vehicle's interior, enhancing its overall appearance while keeping the door edges protected from damage caused by foot traffic or equipment.

Why Do Door Sills Break Down?

Over time, door sills can wear out due to constant exposure to dirt, moisture, and friction. The material, often plastic or metal, can crack, discolor, or become scratched. Lower-quality aftermarket door sills might not fit properly or last as long as genuine parts, leading to quicker breakdowns and less protection for your vehicle.

When Should You Replace Your Door Sills?

It’s time to replace your door sills if you notice cracking, fading, or excessive wear. While these parts are built to last, regular wear and tear from entering and exiting your vehicle can cause them to degrade over time. Regular inspections will help identify when they need replacing, especially if you notice damage that could lead to further issues.
