CURT gooseneck under-bed installation kits can provide both strength and the ideal mounting solution for your gooseneck hitch (sold separately). The laser-cut installation kits work by bolting onto the frame of your truck, typically using pre-existing holes. Once the brackets and rails are firmly secured, then you can attach a gooseneck hitch--providing the strength needed to tow an extra-heavy, oversized trailer. These CURT under-bed gooseneck installation kits are rated to your vehicle's max gross weight capacity.
