For trucks with an aluminum body, such as the Ford F150, galvanic corrosion can become a problem when installing a gooseneck hitch without the appropriate protection. This isolator film allows you to install a CURT gooseneck hitch in your truck bed without having to worry about galvanic corrosion. It is made from 8-mil polyurethane and has an acrylic adhesive backing to remain fixed in place during installation. The isolator film easily fits over the gooseneck platform to isolate the hitch from all aluminum surfaces. It fits most CURT gooseneck hitch models, including all Double Lock and Double Lock EZr models, our OEM-style Ram gooseneck hitches and all Quick Goose II models.
