10 Best Truck Tailgate Seals 2025 in the United States

The ESI ROK BLOCK Tailgate Gap Cover is designed to prevent debris, dust, fumes, and water from entering the tailgate gap area, reducing the need for frequent clean-ups. This 4.25-inch wide tailgate seal is made in the USA and uses high-quality 3M ST1200 tape, ensuring it adheres well to all surface finishes, including spray-on bedliners. It is essential to apply the tape at temperatures between 50° - 104°F for optimal adhesion, requiring 25 lbs. of pressure to bond the adhesive effectively.

The compatibility of this product is quite specific. It fits various trucks, including popular models like the Silverado, Ford F Series, and RAM 2500/3500, but it excludes certain vehicles like the Ford with Pro Access Tailgate and Tesla Cybertruck. This specificity requires users to verify their truck model before purchasing.

Installation is straightforward, especially for those with spray-on bedliners, but it can be slightly more involved for trucks with drop-in liners, as the ROK BLOCK needs to be installed under the liner. While the product does an excellent job of sealing the tailgate gap when closed, users will need an additional Tailgate Seal with Taper Seal (sold separately) to seal the sidewalls completely.

The ESI ROK BLOCK Tailgate Gap Cover is a robust solution for truck owners who want to keep their tailgate gap clean and sealed. Its strong adhesive and weather resistance make it a reliable choice, though compatibility checks and potential additional purchases may be necessary.

The Truck Tonneau Cover Seal from Salior is designed to offer excellent sealing and protection for various vehicles such as pickups, trucks, RVs, and cars. Made from durable EPDM rubber, it excels in flexibility, aging resistance, and can withstand extreme weather conditions. This robust material ensures longevity, making it a reliable choice for keeping your truck quiet and free from rain, dust, and other elements. The double hole design enhances its sealing capabilities, effectively blocking gaps and providing a snug fit for your vehicle’s edges.

Measuring 157.48 inches in length and 1.62 inches in width, it's crucial to measure your specific needs to avoid running short during installation. The product features a strong adhesive backing, which simplifies the installation process to just a few steps - cleaning the surface, peeling the adhesive, and cutting any excess strip. However, users should ensure the surface is thoroughly cleaned to guarantee the best adhesion.

This tailgate seal is a strong contender for those needing durable, easy-to-install weather stripping for their vehicles, but attention to specific fitment is advised. Some might find the 0.45-inch thickness insufficient for larger gaps, and the universal design might not perfectly fit every vehicle type, requiring careful measurement and adjustment.

The ESI Ultimate Tailgate Seal with Taper Seal is designed to be compatible with all Ford model years of F150, F250, F350, F450, Ford Raptor, and Ford Lightning. Its material, automotive-grade EPDM rubber, ensures durability and resistance to weather elements, making it a reliable option for keeping out dust and water when using a truck bed cap or tonneau cover. The 3M ST1200 tape ensures a strong adhesive quality, adhering well to all surface finishes including spray-on bed liners, although it requires specific temperature conditions (55° - 104°F) and 25 lbs. of pressure to bond effectively.

The kit has been upgraded to use fewer cut pieces, simplifying the installation process, which is a notable advantage for users seeking ease of installation. However, it is essential to follow the provided directions carefully to ensure proper application. The seal thickness is designed to fit well with the mentioned Ford models, but it is not compatible with Ford Ranger, Ford Maverick, or Ford trucks with a Pro Access Tailgate, which limits its universal application within the Ford truck range.

Priced reasonably within its category, it has garnered positive feedback with a 4.3 out of 5 stars rating from 214 customer reviews, reflecting satisfaction with its performance and quality. For users with compatible Ford models looking for an effective tailgate seal solution, this product offers solid performance with the caveat of needing careful installation to achieve optimal results.
