Construction & Design

The SillProtector is constructed from a tough, impact-resistant plastic that withstands daily abuse without compromising flexibility or fit. This material is engineered to resist cracking and fading, ensuring long-lasting protection that endures the rigors of off-road adventures and urban driving alike. The precise molding process guarantees a custom fit that hugs the contours of the Jeep Wrangler’s door sills, providing full coverage without interfering with door operation or interior aesthetics.

The adhesive backing uses a very high-bond formula designed to securely attach the protector to the door sill surface while allowing for clean removal if necessary. This thoughtful design balances durability with ease of installation and maintenance.

Installation & Fitment

Installing the WeatherTech SillProtector is straightforward and requires no special tools or modifications. Begin by thoroughly cleaning the door sill surfaces to remove dirt, oils, and debris. Use the included alcohol pad to ensure the surface is perfectly prepared for adhesion. Next, clean the SillProtector itself to remove any contaminants.

Peel back the adhesive liner carefully and press the protector firmly onto the door sill, aligning it precisely with the contours of your Jeep Wrangler. The high-bond adhesive ensures a secure fit that will not shift or peel under normal use. This product fits all 2018–2026 Jeep Wrangler models equipped with 2.0L Turbo, 3.6L V6, 3.0L EcoDiesel, and 6.4L 392 engines, including the 2018 JK generation and the latest JL models.
