Product Details

The ROK BLOCK 4.25″ Tailgate Gap Cover is a patented solution manufactured in the USA since 1999. This product effectively bridges the gap between the truck bed and tailgate, significantly reducing the loss of materials including gravel, dirt, mulch, and sand during transport. When the tailgate is closed, it doubles as a seal, complementing a truck bed cap or tonneau cover to enhance protection against dust, fumes, and water infiltration. Compatibility: This cover is designed for various truck models, including Silverado (excluding EV), Sierra (excluding EV), Ford F Series 2021 and later with a hinge retainer bracket, Ford Lightning, Ford Ranger 2019 and newer, Nissan Frontier, and RAM 2500 and 3500. Note that it is not compatible with certain models such as Ford with Pro Access Tailgate, Honda Ridgeline with Dual Action Tailgate, Hyundai Santa Cruz, RAM with Multifunction Tailgate, Rivian, and Tesla Cybertruck. Installation: The ROK BLOCK installs under drop-in bed liners and requires a temperature range of 50° to 104°F (10° to 40°C) for optimal adhesion. It employs automotive-grade 3M ST1200 tape for secure bonding, necessitating 25 lbs. of pressure for the adhesive to set properly. Additional sealing solutions such as the patented Tailgate Seal with Taper Seal (sold separately, ASIN: B00IPQWXZQ) can be added to provide comprehensive coverage. Product Details:
