Importance of Car Roof Racks If you have factory luggage on the roof, you may want to consider adding a roof rack to your vehicle. Although roof rack crossbars fit roof rack side rails, receiver hitches are another asset to your roof. Besides support, cargo baskets are another option for handling cargo. Roof racks and cargo baskets are a way to locate your gear, items and other tools from one location to another. These cargo baskets are lightweight, made of steel, stackable and are used to transport heavy objects. There are cargo baskets available as needed which are customizable and also come with an open and covered basket. What to choose? Aftermarket or factory roof rack Factory racks are ready to use, manufacturers offer accessories for a range of vehicles such as skis, bikes or kayaks which can be attached directly in the luggage rack. But some vehicles are not equipped with supports. You must therefore opt for an aftermarket rack but they are not sold as a complete kit. Therefore, you need to purchase an individual rack which can be customized according to the requirements. You can find a range of rack options on the aftermarket, even if you want a rack for any classic.
