ESI Ultimate Tailgate Seal with Taper Seal for GMC Sierra MultiPro & Chevrolet Silverado Multi-Flex

Introducing the ESI Ultimate Tailgate Seal with Taper Seal, designed for GMC Sierra with MultiPro Tailgate and Chevrolet Silverado with Multi-Flex tailgates. This precise edge sits along the tailgate gap, forming a flexible barrier that helps reduce the intrusion of dust, dirt, and moisture when you attach a bed cap or tonneau cover. The experience is tactile: a clean, snug interface where the tailgate meets the bed, with a subtle resistance as the seal compresses to a quiet close.

Designed with a 21-foot automotive-grade EPDM rubber profile and backed by a durable 3M ST1200 tape, this seal is built to endure daily use and resist compression over time. It adheres to a variety of surface finishes, including spray-on bed liners, which broadens your installation options without needing special prep steps. In practice, the seal feels soft to the touch but forms a firm barrier once seated, giving a sense of assurance when you seal up the cargo area after a trip or job site.

Real-world scenarios

On a weekend camping trip with a bed cap, the seal helps keep dust, grit, and moisture from seeping into the tailgate seam. After a quick rinse, the EPDM surface wipes clean with minimal effort, thanks to its smooth, resilient texture. During sudden rain, the barrier helps keep the cargo area drier when opening the tailgate at the campsite or on the worksite. For fleet use, this seal offers a consistent level of protection through daily open-close cycles.
